100 euro note, Circulation
The first series of notes were issued in conjunction with those for a few weeks in the series 'Europe' until existing stocks are exhausted, then gradually withdrawn from circulation. Both series thus run parallel but the proportion tends inevitably to a sharp decrease in the first series.

100 euro note, Legal information
Legally, both the European Central Bank and the central banks of the eurozone countries have the right to issue the 7 different euro banknotes. In practice, only the national central banks of the zone physically issue and withdraw euro banknotes. The European Central Bank does not have a cash office and is not involved in any cash operations.


100 euro note, Tracking
There are several communities of people at European level, most of which is EuroBillTracker, that, as a hobby, it keeps track of the euro banknotes that pass through their hands, to keep track and know where they travel or have traveled. The aim is to record as many notes as possible in order to know details about its spread, like from where and to where they travel in general, follow it up, like where a ticket has been seen in particular, and generate statistics and rankings, for example, in which countries there are more tickets. EuroBillTracker has registered over 176 million notes as of May 2018, worth more than €3.257 billion.

100 höjdare
100 höjdare ("100 Highlights") was a Swedish TV series which was produced and aired on Kanal 5. Six seasons of the show were produced and it ran from 2004 to 2008. It was hosted by the comedy duo Filip Hammar & Fredrik Wikingsson.


100 höjdare
In the first three seasons the hosts presented funny moments, often in the form of video clips, listing their 100 all-time favorites. In season two and three they also discuss the clips with celebrity guests. By season four the format changed and instead of showing clips, Filip and Fredrik made impromptu interviews with people, often in their homes.


100 höjdare, Season overview, Original format
The first season, "Sweden's 100 Funniest Moments", first aired on 5 September 2004 and consisted of nine 25 minute episodes. Wikingsson and Hammar presented the clips in a summer-themed outdoor environment.


100 höjdare, Season overview, Original format
The show lists funny moments and people that are not intended to be funny, i.e., no sketches or jokes, etc. The clips are chosen by the hosts and reflect their kind of humour. The well known Swedish sports commentator Bosse Hansson gave voice-overs on the video clips and animations illustrating the funny moments in the first two seasons. The theme song is "Pretty Belinda" by Hammar, Wikingsson and their producer André Linschooten. The trio called themselves Fille and the Fittpippers when releasing the song; the song was originally made by Chris Andrews.


100 höjdare, Season overview, Original format
Season two, first aired on 7 March 2005, consisted of ten 45 minute episodes. The theme for season two was "The World's 100 Funniest Moments". The production was now a bit more expensive and the show took place in a studio with live audience and one or two invited guests for each show. Season two featured a part of the programme entitled "Luca's Ladder", in which Wikingson & Hammars' gay Italian friend Luca Brasi presented one of his favourite clip from the first season.


100 höjdare, Season overview, Original format
Despite its title, season three of 100 höjdare consisted of eight different top ten lists, making it only 80 highlights. As in season two, each episode is 45 minutes and takes place in a studio with guests commenting the clips. Season three first aired on 21 November 2005.


100 höjdare, Season overview, New format
In season four, Fredrik and Filip try to find Sweden's 100 most original people. The winner of each show was invited for a grand finale where an overall winner was selected. Season four first aired on 28 August 2006. Season five, airing in 2007, was similar to season four, but included people from all over Scandinavia.


100 höjdare, Season overview, New format
In season six, first aired on 17 March 2008, they travel around America trying to find "100 reasons to love the United States" in the form of very unusual people. In the last episode, similar to season four and five, they crown "America's most extraordinary person".


100 in a 55
"100 in a 55" is a song by rock band Pop Evil. The song is the second single from the band from Lipstick on the Mirror, the debut studio album from the band.


100 in a 55, Premise
According to Pop Evil lead vocalist Leigh Kakty, the song is similar to recuperation, as it is about focusing on what is optimal for an individual and those close to them. It is about holding one's ground, and asking one's self whether or not they would like to be someone important in the international community. Kakaty goes on to state that the composition touches on viewing one's reflection and combating the demon that one created.


100 kilometres race walk
The 100-kilometer race walk is a racewalking event. The event is competed as a road race. Athletes must always keep in contact with the ground and the supporting leg must remain straight until the raised leg passes it. 100 kilometers is 62.14 miles.


100 kilometres race walk, History
Against the wishes of the Israeli track and field authorities, because the Munich Massacre had just taken place, Israel Shaul Ladany competed and won the gold medal in the World 100 km walking title at the 1972 World Championships in Switzerland, in a time of 9:31:00.


100 kilometres race walk, U.S. record
The United States record is 9:36:33, set by Dan Pierce in Houston, Texas, on December 2, 1987.


100 krooni
The 100 krooni banknote (100 EEK) is a denomination of the Estonian kroon, the former currency of Estonia. Lydia Koidula (1843–1886), who was an Estonian poet and playwright, is featured on the front side of the banknote, which is why the 100 krooni banknote is often called a "Koidula".


100 krooni
A view of the north Estonian limestone shore is featured on the reverse side of the banknote. Before the replacement of the kroon by the euro, the 100 krooni banknote was the main everyday currency used by Estonians and was commonly dispensed by ATMs in Estonia as well as used for withdrawals or cashing checks. It can be exchanged indefinitely at the currency museum of Eesti Pank for €6.39.


100 latinos dijeron
100 latinos dijeron (100 Latinos Said) is the Spanish-language adaptation version of the American program Family Feud, and is also a remake of the short-lived 2006–08 Spanish-language adaptation of Feud called ¿Qué dice la gente? (What Do People Say?). The series, hosted by Marco Antonio Regil who also previously hosted ¿Que dice la gente? from 2006 until 2008 and 100 mexicanos dijeron from 2001 until 2006 respectively was transmitted by MundoMax (formerly MundoFox), premiered on September 9, 2013. This show was cancelled in 2016 due to its network, MundoMax, being dissolved.


100 latinos dijeron
In 2018, it was announced that Estrella TV had signed a multi-year licensing agreement with Fremantle to revive the show. It is planned to debut in the early part of 2019. On February 12, 2019, it was announced that the revival will be hosted by Armando Hernández and would premiere on Estrella TV on February 19. On August 1, 100 Latinos dijeron for renewed for a second season and started adding comedian Mau Nieto as new host replacing Armando Hernandez.


100 latinos dijeron, Gameplay
In each episode, two families compete among themselves for a large sum of money, trying to guess responses from a survey of one hundred people. The fourth question is worth double points and each question thereafter is worth triple points. The sixth question, if necessary, features only the top answer on the board. Two members of the first family to reach 300 points then play in a bonus round entitled "Dinero Rapido," where they must answer five questions and score two hundred points to win the top prize. The first player must answer within 20 seconds and the second player must answer within 25 seconds. If they scored less that 200 points, the family would be given $500. The jackpot would start at $10,000 and increase by $1,000 for each loss up to a maximum of $25,000.


100 latinos dijeron, Gameplay
Two new families competed in the first half-hour and the winners competed against the champions in the second half-hour.


100 latinos dijeron, Gameplay
On the 2019 revival, the winning family plays for $5,000. Failure to reach 200 points in Dinero Rapido earns the family $500.


100 m running moose
100 meter running moose (Norwegian elgbaneskyting, Swedish älgbaneskytte, Finnish hirviammunta) is a shooting sport based on running targets simulating a moose moving sideways.


100 m running moose
The sport is popular in Norway, Sweden and Finland, with competitions being arranged by the Norwegian Association of Hunters and Anglers, Svenska Jägareförbundet and Finnish Hunters' Association, respectively. Events are most commonly shot at 100 meters, but sometimes 80 meters instead (particularly in Sweden). The use of electronic targets is common, but cardboard targets are also sometimes used.


100 m running moose, History
In the 1950s, many shooting ranges in Norway had already been set up for training on running moose targets, but it was first introduced as a competition in the 1960s by the Norwegian Association of Hunters and Anglers. Interest increased steadily, and in the 1980s over 130 shooting ranges across Norway were set up for running moose.


100 m running moose, History
In Hordaland and Sogn og Fjordane in Western Norway, it was for long common to change the running moose targets with one of a running deer with the same hit zones and points, since there is little moose and a lot of red deer in those regions. Nowadays, most ranges have changed to standard moose targets.


100 m running moose, Program
A match consists of 20 fired rounds. The first 10 rounds are shot at a static target, while the last 10 rounds are fired at a moving target. Both the static and running target have an inner hit zone, denoted with a star (*), used to distinguish the best shooters.


100 m running moose, Program, Static target
The 5 first rounds at the static target are fired from a seated position, which is to be completed during a 2 minute string. The next 5 rounds are fired at the same target, but from a standing position, also within a 2 minute string.


100 m running moose, Program, Static target
The static target stage has available a maximum of 50 points with 10 inside hits, called "50-10", and this forms a basis before the running target shooting event.


100 m running moose, Program, Running target
The moving target string consists of 10 rounds. The target moves sideways with a velocity of approximately 5 m/s (18 km/h; 11 mph), appearing from cover and disappearing after each pass. The target can only be engaged with one round for each of its ten passes. With the visible opening being around 20-25 meters wide, this means that the moose is visible for around 4-5 seconds during each pass.


100 m running moose, Program, Running target
The moving target stage has available a maximum of 50 points with 10 inside hits, called "50-10".


100 m running moose, Program, Combined score
The combined maximum points for a match is 100 points with 20 inside hits, called "100-20".


100 m running moose, Equipment
Competitors are divided into several classes based on equipment, age and previous accomplishments.


100 m running moose, Equipment, Nordic Championship rules
In the Nordic championships, there is only one equipment class, and competitors are divided into the classes senior, D2, E1, E2 and F. Here the minimum bullet diameter is 6.5 mm (i.e. 6.5x55 mm or 6.5x47 mm), the minimum trigger pull is 1 kg, and the rifle can weigh maximum 5.5 kg.


100 m running moose, Equipment, National Norwegian rules
Competitions in Norway (except Nordic championships) divide competitors into the following set of classes:


100 m running moose, Equipment, National Norwegian rules
The sporter class has no maximum weight for the rifle, and it is common to use heavy "sporter rifles". The minimum trigger pull weight i 1 kg. The smallest permitted cartridge is .222 Rem (since 1 January 2015, formerly the minimum bullet diameter was 6.5 mm). Some of the most commonly seen cartridges in competitions are .223 Remington, 6.5×55 mm, .308 Win and .30-06. Scopes can be chosen freely, regardless of magnification.


100 m running moose, Equipment, National Norwegian rules
The hunter class (jegerklassen) was originally aimed at typical hunting rifle setups, but today most compete with special built competition rifles. There is a maximum weight of 5 kg for the rifle, and scope sights can have a 12x maximum magnification. As with the sporter class, the minimum trigger pull is 1 kg, and the smallest permitted cartridge i .222 Rem. The cartridges most commonly seen in competitions are the same as for the sporter class.


100 m running moose, Equipment, National Norwegian rules
Younger junior (yngre junior) permits any cartridge, and it is common to see participants shooting .22 LR, .223 Remington, 6.5×55 mm, .308 Win or .30-06. As for the other classes, the minimum trigger pull weight is 1 kg. There is no weight limit on the firearm, and scope sights can be chosen freely.


100 manat
100 manat - (Azerbaijani: Yüz manat, Turkmen: Ýüz manat) is the one of banknotes in Azerbaijan and Turkmenistan.


100 meter running deer
100 meter running deer is a discontinued ISSF shooting event, that was part of the Olympic program from 1908 to 1924, in 1952 and 1956, and of the ISSF World Shooting Championships program from 1929 to 1962, when it was replaced by 50 meter running target. Being the original running target event, it was shot with centerfire rifles from a distance of 100 meters, with the target moving sideways across a 20-meter-wide opening. There were two versions: single shot and double shot. Occasionally combined competitions, with half the course fired single-shot and half double-shot, were held instead of or in addition to the others. The Nordic Shooting Region continued to hold championships in the discipline until 2004.


100 meter running deer, History, In the Olympics
1908 was the first time of running deer at the Olympics, and the target was specified to placed at 110 yards (100.584 meters) and made 10 runs of 75 feet (22.86 meters) for about 4 seconds each. The deer target a scoring area of three concentric circles, with the smallest counting for 4 points, the middle for 3, and the outermost for 2. A hit outside the circles but still on the target (except on the haunch) counted for 1 point.


100 meter running deer, History, In the Olympics
The target made 10 runs for each shooter both in the Single- and Double-Shot event, and in the Team event each team consisted of four shooters. Thus the individual double-shot event a maximum of 80 points per shooter, the Individual Single-Shot event had a maximum 40 points per shooter, and the Team Single-Shot event had a maximum of (4·40 =) 160 points per team.


100 meter running deer, History, In the Olympics
In the 1912 event the target had been changed to have 5 scoring areas, with 5 point for inner scoring area. The target distance was now specified as 100 meters. Each shooter still got 10 runs, and thus the maximum possible points thus became maximum 100 points for Individual Double-Shot, 50 for Individual Single-Shot and 200 for Team Single-Shot respectively. 20 shooters from 6 nations competed in the Individual Double-Shot event, 20 shooters from 5 nations competed in the Team Single-Shot event, and 34 sport shooters from 7 nations competed in the Team Single-Shot event.


100 meter running deer, History, In the Olympics
In 1920 the events were held on 27 July. 8 shooters from 3 nations competed in the Individual Double-Shot event, while 12 shooters from 4 nations competed in the Individual Single-Shot event. This championship saw the introduction of the Team Double-Shot event, now in addition to the Team Single-Shot event. 20 shooters from four nations competed in both these events.


100 meter running deer, History, In the Olympics
In 1924 the events were held from 30 June to 3 July at the shooting range in Le Stand de Tir de Versailles in Versailles, France. The number, types and format of the events was similar as in the 1920 Olympics. First out was the Individual Single-Shot event in 30 June where 32 shooters from 8 nations competed. The day after on 1 July the Individual Double-Shot event was held, with 31 shooters from 8 nations. The last two days consisted of the Team events. Team Single-Shot was held on 2 July with 25 shooters from 7 nations.


100 meter running deer, History, In the Olympics
Notably, Czechoslovakia was allowed to compete with an incomplete team; only one shooter participated. Lastly the Team Double-Shot event was held on 3 July, with 25 shooters from 7 nations. Notably Hungary was allowed to compete with an incomplete team; only one shooter participated. Running deer events would not be held again at the Olympics until 1952, meaning that the event was not included in the 1928, 1932, 1936 and 1948 Summer Olympics. 1924 would also be the last time of format with separate Single- and Double-Shot events, as well as any Team events.


100 meter running deer, History, In the Olympics
In the 1952 Olympics in Helsinki, Finland, running deer was again on the olympic program, but this time in the new format of the Individual Combined Single- and Double-Shot event only. The competition was held on 28 and 29 July, and 14 shooters from 7 nations competed. The winner, John Larsen from Norway, scored 413 points.


100 meter running deer, History, In the Olympics
In the 1956 Summer Olympics in Melbourne, Australia was again arranged in the format of an Individual Combined Single- and Double-Shot event on 3 and 4 December. 11 shooters from 6 nations competed. The winner, Vitali Romanenko from Ukrainia and competing for the Soviet Union, scored 441 points. This was the last time running deer was arranged as a part of the Olympics.


100 metres
The 100 metres, or 100-metre dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, the 100-metre dash is one of the most popular and prestigious events in the sport of athletics. It has been contested at the Summer Olympics since 1896 for men and since 1928 for women. The World Championships 100 metres has been contested since 1983.


100 metres
The reigning 100 m Olympic or world champion is often named "the fastest man or woman in the world". Christian Coleman and Shelly-Ann Fraser-Pryce are the reigning world champions; Marcell Jacobs and Elaine Thompson-Herah are the men's and women's Olympic champions.


100 metres
On an outdoor 400 metres running track, the 100 m is run on the home straight, with the start usually being set on an extension to make it a straight-line race. There are three instructions given to the runners immediately before and at the beginning of the race: "on your marks," "set," and the firing of the starter's pistol. The runners move to the starting blocks when they hear the 'on your marks' instruction.


100 metres
The following instruction, to adopt the 'set' position, allows them to adopt a more efficient starting posture and isometrically preload their muscles: this will help them to start faster. A race-official then fires the starter's pistol to signal the race beginning and the sprinters stride forwards from the blocks. Sprinters typically reach top speed after somewhere between 50 and 60 m. Their speed then slows towards the finish line.


100 metres
The 10-second barrier has historically been a barometer of fast men's performances, while the best female sprinters take eleven seconds or less to complete the race. The current men's world record is 9.58 seconds, set by Jamaica's Usain Bolt in 2009, while the women's world record of 10.49 seconds set by American Florence Griffith-Joyner in 1988 remains unbroken.


100 metres
US athletes have won the men's Olympic 100 metres title more times than any other country, 16 out of the 28 times that it has been run. US women have also dominated the event, winning 9 out of 21 times.


100 metres, Race dynamics, Start
At the start, some athletes play psychological games such as trying to be last to the starting blocks.


100 metres, Race dynamics, Start
At high level meets, the time between the gun and first kick against the starting block is measured electronically, via sensors built in the gun and the blocks. A reaction time less than 0.1 s is considered a false start. The 0.2-second interval accounts for the sum of the time it takes for the sound of the starter's pistol to reach the runners' ears, and the time they take to react to it.


100 metres, Race dynamics, Start
For many years a sprinter was disqualified if responsible for two false starts individually. However, this rule allowed some major races to be restarted so many times that the sprinters started to lose focus. The next iteration of the rule, introduced in February 2003, meant that one false start was allowed among the field, but anyone responsible for a subsequent false start was disqualified.


100 metres, Race dynamics, Start
This rule led to some sprinters deliberately false-starting to gain a psychological advantage: an individual with a slower reaction time might false-start, forcing the faster starters to wait and be sure of hearing the gun for the subsequent start, thereby losing some of their advantage. To avoid such abuse and to improve spectator enjoyment, the IAAF implemented a further change in the 2010 season – a false starting athlete now receives immediate disqualification. This proposal was met with objections when first raised in 2005, on the grounds that it would not leave any room for innocent mistakes. Justin Gatlin commented, "Just a flinch or a leg cramp could cost you a year's worth of work." The rule had a dramatic impact at the 2011 World Championships, when current world record holder Usain Bolt was disqualified.


100 metres, Race dynamics, Mid-race
Runners normally reach their top speed just past the halfway point of the race and they progressively decelerate in the later stages of the race. Maintaining that top speed for as long as possible is a primary focus of training for the 100 m. Pacing and running tactics do not play a significant role in the 100 m, as success in the event depends more on pure athletic qualities and technique.


100 metres, Race dynamics, Finish
The winner, by IAAF Competition Rules, is determined by the first athlete with their torso (not including limbs, head, or neck) over the nearer edge of the finish line. There is therefore no requirement for the entire body to cross the finish line. When the placing of the athletes is not obvious, a photo finish is used to distinguish which runner was first to cross the line.


100 metres, Race dynamics, Climatic conditions
Climatic conditions, in particular air resistance, can affect performances in the 100 m. A strong head wind is very detrimental to performance, while a tail wind can improve performances significantly. For this reason, a maximum tail wind of 2.0 m/s is allowed for a 100 m performance to be considered eligible for records, or "wind legal".


100 metres, Race dynamics, Climatic conditions
Furthermore, sprint athletes perform a better run at high altitudes because of the thinner air, which provides less air resistance. In theory, the thinner air would also make breathing slightly more difficult (due to the partial pressure of oxygen being lower), but this difference is negligible for sprint distances where all the oxygen needed for the short dash is already in the muscles and bloodstream when the race starts. While there are no limitations on altitude, performances made at altitudes greater than 1000 m above sea level are marked with an "A".


100 metres, 10-second barrier
The 10-second mark had been widely considered a barrier for the 100 metres in men's sprinting. The first man to break the 10 second barrier was Jim Hines at the 1968 Summer Olympics. Since then, numerous sprinters have run faster than 10 seconds.


100 metres, 10-second barrier, Ethnicity
Only male sprinters have beaten the 100 m 10-second barrier, the vast majority of them being of West African descent. Namibian (formerly South-West Africa) Frankie Fredericks became the first man of non-West African heritage to achieve the feat in 1991 and in 2003 Australia's Patrick Johnson (an Indigenous Australian with Irish heritage) became the first sub-10-second runner without an African background.


100 metres, 10-second barrier, Ethnicity
In 2010, French sprinter Christophe Lemaitre became the first Caucasian to break the 10-second barrier. In 2017, Azerbaijani-born naturalized Turkish Ramil Guliyev followed and in 2018, Filippo Tortu became the first Italian to run under 10s. In the Prefontaine Classic 2015 Diamond League meet at Eugene, Su Bingtian of China ran a time of 9.99 seconds, becoming the first East Asian athlete to officially break the 10-second barrier. On 1 August 2021, Su improved his Asian record at the Olympic semifinal in Tokyo with a time of 9.83.


100 metres, 10-second barrier, Ethnicity
On 9 September 2017, Yoshihide Kiryū became the first man from Japan to break the 10-second barrier in the 100 metres, running a 9.98 (+1.8) at an intercollegiate meet in Fukui. British sprinter Adam Gemili, an athlete with an Iranian-Moroccan ethnic background, became the first sprinter of Middle-Eastern and North African ancestry to legally break the barrier on 7 June 2015, having done so earlier in the same season with an excessive wind reading.


100 metres, Record performances
Major 100 m races, such as at the Olympic Games, attract much attention, particularly when the world record is thought to be within reach.


100 metres, Record performances
The men's world record has been improved upon twelve times since electronic timing became mandatory in 1977. The current men's world record of 9.58 s is held by Usain Bolt of Jamaica, set at the 2009 World Athletics Championships final in Berlin, Germany on 16 August 2009, breaking his own previous world record by 0.11 s. The current women's world record of 10.49 s was set by Florence Griffith-Joyner of the US, at the 1988 United States Olympic Trials in Indianapolis, Indiana, on 16 July 1988 breaking Evelyn Ashford's four-year-old world record by .27 seconds.


100 metres, Record performances
The extraordinary nature of this result and those of several other sprinters in this race raised the possibility of a technical malfunction with the wind gauge which read at 0.0 m/s- a reading which was at complete odds to the windy conditions on the day with high wind speeds being recorded in all other sprints before and after this race as well as the parallel long jump runway at the time of the Griffith-Joyner performance.


100 metres, Record performances
All scientific studies commissioned by the IAAF and independent organisations since have confirmed there was certainly an illegal tailwind of between 5 m/s – 7 m/s at the time. This should have annulled the legality of this result, although the IAAF has chosen not to take this course of action. The legitimate next best wind legal performance would therefore be Griffith-Joyner's 10.61s performance in the final the next day.


100 metres, Record performances
Some records have been marred by prohibited drug use – in particular, the scandal at the 1988 Summer Olympics when the winner, Canadian Ben Johnson was stripped of his medal and world record.


100 metres, Record performances
Jim Hines, Ronnie Ray Smith and Charles Greene were the first to break the 10-second barrier in the 100 m, all on 20 June 1968, the Night of Speed. Hines also recorded the first legal electronically timed sub-10 second 100 m in winning the 100 metres at the 1968 Olympics. Bob Hayes ran a wind-assisted 9.91 seconds at the 1964 Olympics.


100 metres, All-time top 25 men, Assisted marks
Any performance with a following wind of more than 2.0 metres per second is not counted for record purposes. Below is a list of the fastest wind-assisted times (equal or superior to 9.80). Only times that are superior to legal bests are shown:

100 metres at the Olympics
The 100 metres at the Summer Olympics has been contested since the first edition of the multi-sport event. The men's 100 m has been present on the Olympic athletics programme since 1896. The 100 metres is considered one of the blue ribbon events of the Olympics and is among the highest profile competitions at the games. It is the most prestigious 100 m race at elite level and is the shortest sprinting competition at the Olympics – a position it has held at every edition except for a brief period between 1900 and 1904, when a men's 60 metres was contested.


100 metres at the Olympics
The first Olympic champions were Thomas Burke in the men's category and, 32 years later, Betty Robinson in the women's category. The Olympic records for the event are 9.63 seconds, set by Usain Bolt in 2012, and 10.61 seconds, set by Elaine Thompson-Herah in 2021. The world records for the event have been equalled or broken during the Olympics on seven occasions in the men's category and on twelve occasions in the women's.


100 metres at the Olympics
Among the competing nations, the United States has had the most success in this event, having won sixteen golds in the men's race and nine in the women's race. Usain Bolt of Jamaica has won three consecutive titles (2008–16). Five other athletes have won back-to-back titles: Wyomia Tyus (1964–68), Carl Lewis (1984–88), Gail Devers (1992–96), Shelly-Ann Fraser-Pryce (2008–12), and Elaine Thompson-Herah (2016-2020). Merlene Ottey is the only athlete to win three medals without winning gold, with one silver and two bronze medals. Shelly-Ann Fraser-Pryce is the most decorated athlete in the event, male or female, having won 4 medals.


100 metres at the Olympics
Many athletes that compete in this event also compete individually in the Olympic 200 metres and with their national teams in the Olympic 4×100 metres relay, with Jamaicans Usain Bolt and Elaine Thompson-Herah being the only athletes to do so more than once. Nine men have achieved the 100 metres and 200 metres 'Double' at the same Olympic Games - Archie Hahn (1904), Ralph Craig (1912), Percy Williams (1928), Eddie Tolan (1932), Jesse Owens (1936), Bobby Morrow (1956), Valeriy Borzov (1972), Carl Lewis (1984), and Usain Bolt (2008, 2012, 2016).


100 metres at the Olympics
Four of these men were also members of the winning team in the 4x100 meters relay at the same games - Jesse Owens (1936), Bobby Morrow (1956), Carl Lewis (1984), and Usain Bolt (2012, 2016). Two of these men have won a fourth gold medal at the same games - Archie Hahn in the now defunct 60 metres, and both Jesse Owens and Carl Lewis in the long jump.


100 metres at the Olympics
Seven women have achieved the 100 metres and 200 metres 'Double' at the same Olympic Games - Fanny Blankers-Koen (1948), Marjorie Jackson (1952), Betty Cuthbert (1956), Wilma Rudolph (1960), Renate Stecher (1972), Florence Griffith-Joyner (1988), and Elaine Thompson-Herah (2016) and (2021). Four of these women were also members of the winning team in the 4x100 meters relay at the same games - Fanny Blankers-Koen (1948), Betty Cuthbert (1956), Wilma Rudolph (1960), and Florence Griffith-Joyner (1988). Fanny Blankers-Koen is the only one of these women to win four gold medals at the same games by winning the 80 metres hurdles in 1948.


100 metres at the Olympics, Competition format
The Olympic 100 metres competitions are carried out under standard international rules, as set by the International Association of Athletics Federations (IAAF). The races are segregated by gender, with one for men and one for women. The 100 m is usually held at the beginning of the Olympic athletics programme as this allows athletes to compete in other events held later at the games – many 100 m athletes also compete in the 200 metres and the 4×100 metres relay events.


100 metres at the Olympics, Competition format
Traditionally there are four rounds of competition: heats, quarter-finals, semi-finals, and finals. Prior to 1964, finals featured six athletes. For all Olympic competitions from 1964 onwards—allowing for a sufficient number of athletes being present—each race features eight runners. Athletes are seeded by past performance to ensure an even balance of quality across the heats and allow the best runners to progress to the later stages. Usually in the first two rounds the top three runners progress to the next stage. A small number of other athletes also progress as the fastest non-qualifiers (or "fastest losers") through a repechage system. Prior to 2012, the semi-finals stage comprised two races of eight athletes and the top four finishers in each race (regardless of time) were entered into the final.


100 metres at the Olympics, Competition format
Several amendments were made to the competition format in 2012. Any participant not in possession of an Olympic qualifying standard time is entered into the preliminary round. Qualifiers in this round progress to the first round proper. The semi-finals stage is divided into three races: the top two progress to the final by right and the two fastest non-qualifiers complete the eight finalists. Changes to the international false start rules were also introduced – any validly recorded reaction time to the starter's pistol of below 0.1 seconds will result in instant disqualification. At the 2004 and 2008 Olympics one false start was allowed per race, with any subsequent false start resulting in disqualification for the offending athletes. At Olympics prior to 2004 each athlete was allowed one false start, with a second false start leading to removal from the field.


100 metres at the Olympics, Competition format
The top three finishers in the final are awarded a gold, silver and bronze medal, respectively. If runners cannot be separated by their time (recorded to one hundredth of a second) further analysis is used to distinguish their times to the thousandth of a second. In the 2008 Women's 100 m final the minor medallists Sherone Simpson and Kerron Stewart could not be separated by this method and were both awarded the silver medal. Medal positions in a 100 m race have only been shared on one other occasion in Olympic history: Alajos Szokolyi and Francis Lane were joint third at the 1896 men's final.


100 metres at the Olympics, Participation
Starting with 15 men from eight nations at the inaugural 1896 Olympic 100 m, participation in the event reached its peak at the 2000 Sydney Games, where 179 male and female athletes from 100 nations were present. The number of competitors and nations in the event has seen an increasing historical trend. This increase has been mostly linear, though participation was affected by the Olympic boycotts of 1976, 1980 and 1984. The linear trend stopped after the 2000 peak and has steadily decreased in subsequent Summer Olympics.


100 metres at the Olympics, Participation
Men's participation reached its highest at the 1996 Atlanta Olympics, which featured 104 men from 75 nations. Women's participation began in 1928, with 31 women from 13 nations competing, and reached an all-time high at the 2008 Beijing Games, which had 85 women representing 69 nations. The 2008 and 2012 editions reversed the historical gender bias towards male participation, as women outnumbered men at the Olympic 100 m for the first time.


100 metres at the Olympics, Participation
As the governing body for the sport of athletics, the International Association of Athletics Federations (IAAF) applies qualifying standards to the competition. This aims to encourage high level performances at the Olympic Games and contain the number of potential entries (the IAAF aims to cap Olympic participation in athletics events at 2000 athletes). There are two types of qualifying standard: the "A" standard and the "B" standard. Each National Olympic Committee (NOC) may enter up to three athletes who have obtained the "A" standard, or one athlete with the "B" standard.


100 metres at the Olympics, Participation
If a NOC has no qualifying athletes in any Olympic athletic event, it may enter one non-qualified athlete – the 100 m is a frequent choice for this type of entry given the brevity of the event. Athletes must achieve the qualifying time without wind-assistance at an officially authorised event within a certain time period, which typically begins from the year prior to the Olympics and extends up to three weeks before the games. The IAAF prohibits entrants who do not reach the age of sixteen in that Olympic year, but there is no upper age limit. The IAAF qualifying standards for the 100 m have become progressively more stringent since 2000.


100 metres at the Olympics, Participation
On top of IAAF standards, national governing bodies may apply their own participation restrictions. These principally come in four forms: stricter national qualifying times, reduced time periods for qualifying performances, performances in the event at a national Olympic trials, and decisions of national selection committees. Smaller nations do not typically apply these additional criteria due to the smaller numbers of sprinters eligible to compete. Larger nations, and nations with strong traditions in sprinting, often have long-running histories of Olympic 100 m trials (such as at the United States Olympic Trials). Participation for a country also demands that the athlete hold respective citizenship and is not subject to a competitive ban through anti-doping rules.


100 metres at the Olympics, Participation
World Athletics in 2019 announced that, following the inauguration of their World Rankings platform, that in addition to those who achieved the Olympic standard, placing in the top 32 of the rankings will serve as a qualification method for athletes. (For example, if someone comes 3rd in the 100m finals of their national championships in 10.14, if he is 22nd in the World Rankings, he has qualified for the games).


100 metres at the Olympics, Biological factors, Age
The 100 m requires a high level of athleticism and as a result most of the participants in the Olympics are aged between 18 and 35 – which is roughly contiguous with the period of peak physical fitness in humans. Consequently, the vast majority of participants in the Olympic 100 m fall within this age range. As of 2020, the qualification rules prohibit athletes younger than 16 at the end of the year of the Games.


100 metres at the Olympics, Biological factors, Age
The record for the youngest athlete to participate in the Olympic 100 m is held by Katura Marae, who was 14 when she represented Vanuatu at the 2004 Athens Olympics. Merlene Ottey holds the records for both the oldest participant and the oldest medallist, having won bronze at age 40 in 2000 and reached the Olympic semi-finals four years later. (Ottey is also the most frequent participant having competed in the Olympic 100 m an unrivalled six times from 1984 to 2004). The first women's champion, Betty Robinson in 1928, remains the youngest gold medallist for the event at 16 years old, while a 32-year-old Linford Christie became the oldest 100 m Olympic champion in 1992.


100 metres at the Olympics, Biological factors, Gender
Since introduction of testing by the IAAF in the early-20th century, female sprinters may be subject to gender verification. This rule was first formally applied to the 100 m at the 1968 Mexico Olympics. No 100 m sprinter has been publicly barred at an Olympic competition. However, there have been historic cases involving two women's medallists: 1932 champion Stanisława Walasiewicz and 1964 bronze medallist Ewa Kłobukowska, both of Poland. Walasiewicz endured accusations during her career due to her appearance, but was never subject to a test. An autopsy following her death in a shooting revealed ambiguous genitalia.


100 metres at the Olympics, Biological factors, Gender
Walasiewicz accused Helen Stephens (who beat her in the 1936 final) of being male and, despite there being no relevant rules on the matter, officials performed a physical examination of Stephens' external genitalia and concluded that she was female. Kłobukowska was not tested at the Olympics, thus did not lose her Olympic medals, but was subsequently disqualified at the 1967 European Cup on the basis of having a chromosomal mosaic. Intersex athletes are restricted from competition in the 100 m without having undergone surgery and hormonal therapy, as a result of the 2003 Stockholm consensus ruling by the IOC.


100 metres at the Olympics, Biological factors, Race
Olympic 100 m medallists in the early editions of the Modern Olympic Games were principally white, Western sprinters of European descent, largely reflecting the make up of the nations that took part. As the Olympic competition began to attract wider international participation, athletes with African heritage began to reach the 100 m Olympic podium, particularly African-Americans and Afro-Caribbeans.


100 metres at the Olympics, Biological factors, Race
Eddie Tolan became the first non-white winner of the event in 1932 and this signified the start of a prolonged period of success by black male sprinters; since 1932 only five men's Olympic champions in the event have not had significant African heritage. The women's event was dominated by runners of European descent until Wilma Rudolph won the title in 1960. Soviet and German women returned to the podium in the period from 1972 to 1980, but since then African-American and Jamaican women have won the great majority of 100 m medals. Dominance in the men's event has been particularly pronounced from 1984 to 2016, during which time all the men's Olympic 100 m finalists have been of African heritage. In the 2020 games, Su Bingtian became the first athlete without African heritage to reach the final since 1984.


100 metres at the Olympics, Biological factors, Race
Most commentators attribute this statistical discrepancy to genetic rather than to cultural factors.


100 metres at the Olympics, Doping
All athletes who participate in the Olympic 100 m competition are subject to the World Anti- Doping Code –the IAAF and International Olympic Committee (IOC) are both signatories. Mandatory in-competition drug testing was introduced at the 1968 Summer Olympics.


100 metres at the Olympics, Doping
One of the most prominent cases of doping at the Olympics, and in sport as a whole, occurred during the 1988 Seoul Olympics. Ben Johnson entered the race as the reigning 100 metres world record holder and won the Olympic final, raising his arm in victory, in a new world record of 9.79 seconds to much fanfare. Soon after being awarded the gold medal the results of his post-race drug test revealed his urine contained traces of stanozolol (a banned steroid).


100 metres at the Olympics, Doping
Johnson later admitted to doping, but he and his coach Charlie Francis still claimed he had his drink spiked at the Olympics, as Johnson was taking a different type of steroid at the time. The positive test had long-lasting effects on public perception of the sport and advanced the case for more stringent drug testing. The Canadian government launched an investigation into drugs in sport, known as the Dubin Inquiry, the following year. The 1988 Olympic men's 100 metres final has been referred to as "the dirtiest race in history", as only two of the eight finalists remained free of doping issues during their careers.


100 metres at the Olympics, Doping
Ekaterini Thanou, the 2000 women's silver medallist, was barred from the 2004 Athens Olympics after failing to attend a pre-competition drugs test (her third consecutive missed test). The Greek sprinter and her teammate Kostas Kenteris were convicted of staging a motorcycle crash to avoid the test, but this was overturned on appeal. Her doping ban remained as they admitted to having missed the tests.


100 metres at the Olympics, Doping
Tameka Williams was banned from competing in the 100 m at the 2012 Olympics when, at the Olympic village, she admitted to the Saint Kitts and Nevis management team that she had been ingesting a banned substance. Bulgaria's Tezdzhan Naimova had her 2008 Olympic performance annulled and received a two-year ban after it was proved that she had tampered with her drug test a month prior to the competition.


100 metres at the Olympics, Doping
Another high-profile doping case involved the 2000 Olympic women's 100 m champion Marion Jones, though no doping infractions occurred during the Olympics. Having been one of the stars of the games—she won three gold and two bronze medals in track and field events—Jones was later implicated in doping through the BALCO scandal. She lied to federal agents and a grand jury during questioning around the scandal, but later admitted in 2007 to using Tetrahydrogestrinone (THG) during the period of her Olympic success. The IOC annulled all her Olympic results, including her 100 m title.


100 metres at the Olympics, Doping
Given that the 2000 women's runner-up Ekaterini Thanou had herself been banned for drug usage, the IOC chose not to upgrade her to the gold medal position, but rather leave the position vacant. Working around the dilemma, the IOC decided to raise bronze medallist Tayna Lawrence to joint silver and fourth-placed Merlene Ottey to the bronze medal position.


100 metres at the Olympics, Doping
In spite of the relatively few occasions in which 100 m sprinters have failed doping tests at the Olympics, numerous Olympic sprinters have been banned outside the competition or implicated otherwise, including many medallists. Two-time Olympic champion Carl Lewis had a positive drug test for stimulants at the US Olympic trials. The United States Olympic Committee accepted his claim of inadvertent use, since a dietary supplement he ingested was found to contain "Ma huang", the Chinese name for Ephedra (ephedrine is known to help weight loss). The 1992 Olympic champion Linford Christie was banned for nandrolone later in his career.


100 metres at the Olympics, Doping
Angel Guillermo Heredia accused the 2000 Olympic champion Maurice Greene of doping; Greene denied this but admitted to paying for "stuff" for his training mates. Justin Gatlin, the men's gold medallist in 2004, served a doping suspension both before and after his Olympic win, and returned to the podium at the 2012 Olympics. The men's runner-up in 2012, Yohan Blake, was banned for consuming a stimulant in 2009.


100 metres at the Olympics, Doping
On the women's side, the Olympic 100 m was affected by state-sponsored doping in East Germany. Stasi documents released after the fall of the Berlin Wall revealed extensive drug usage by Olympic sprinters, including the 1976 and 1980 silver medallists Renate Stecher and Marlies Göhr, as well as the 1988 bronze medallist Heike Drechsler. Shelly-Ann Fraser, twice Olympic champion, received a six-month ban in 2010 for taking a prohibited narcotic for pain relief.


100 metres at the Olympics, Doping
A similar system was in place in the Soviet Union with major revelations concerning the Soviet state-sponsored doping program in preparation for the 1984 Olympics coming to light in 2016. The 2008 runner-up Sherone Simpson was banned in 2013 after a positive test for a stimulant and two-time bronze medallist Veronica Campbell-Brown failed a test for a diuretic that same year. A fourth Jamaican medallist, Merlene Ottey, received a ban for the steroid nandrolone in 1999 but this was rescinded on appeal due to laboratory errors.


100 metres at the Olympics, Olympic record progression
The best time for the 100 m set during Olympic competition is known as the Olympic record. To count as an official record, the race and the equipment used must adhere to IAAF international rules. Hand-timed results were the standard until 1975, when fully automatic timing (FAT) became the preferred method for officially measuring athletes' times. Further to this wind conditions must be measured and any time achieved with a wind speed of over 2.0 metres per second in a direction behind the athlete is treated as wind-assisted and cannot be taken for an Olympic record mark.


100 metres at the Olympics, Olympic record progression
Since the first men's Olympic record of 12.2 seconds by Frank Lane in 1896, the record has been broken 13 times and matched 24 times. Twenty-eight men have been holder (or co-holder) of the record. Usain Bolt is the current record holder with 9.63, set in 2012. Further to this standing men's world record for the 100 m has been equalled five times in Olympic competition and improved twice (by Carl Lewis in 1988 with 9.92 and by Bolt in 2008 with 9.69). Ben Johnson's time of 9.79 was annulled before it was ratified as either an Olympic or world record.


100 metres at the Olympics, Olympic record progression
Since the initial women's Olympic record of 13.0 seconds was set by Anni Holdmann in 1928, it has been broken 18 times and equalled 17 further times. The standing women's 100 m world record has been improved five times during Olympic competition and equalled seven times.


100 metres at the Olympics, Olympic record progression
The tables below refer to hand-timing for races held prior to the 1972 Summer Olympics and to fully automatic times after that point, when they became the standard for the Olympics. Hand-timed results that matched the Olympic record are treated as equalling the mark, with the exception of any athletes that matched that time but finished behind another athlete in their race.


100 metres at the Olympics, Finishing times
The Olympic 100 m is the most prestigious competition for the distance and it attracts elite level, international competitors. The winner of the race is occasionally referred to as "the world's fastest" man or woman, reflecting the high level of the competition and the quality of performances. As of February 2014, the current Olympic records of 9.63 for men and 10.62 seconds for women rank as the second and third fastest times in history, for men and women respectively.


100 metres at the Olympics, Finishing times
The standard of performances at the Olympics has progressed in line with the discipline as a whole and the times in the final often rank highly in the end-of-season lists. National records and personal bests are frequently improved at the event by sprinters from large and small nations alike, as most elite athletes aim to reach peak race fitness for the Olympics.


100 metres at the Olympics, Finishing times
The 2012 men's final was the fastest 100 m race in history, collectively: the top five men ran under 9.90 seconds for the first time ever and seven of the eight finalists ran under 10 seconds (the last runner suffered an injury). Tyson Gay became the fastest non-medallist in history at that race with his time of 9.80 seconds.


100 metres at the Olympics, Finishing times
Similarly, the 2012 women's final was, collectively, the fastest women's 100 m race ever: seven of the eight finalists ran 11 seconds or faster for the first time, with Veronica Campbell-Brown becoming the fastest ever bronze medallist with her time of 10.81 seconds and Tianna Madison becoming the fastest non-medallist with her time of 10.85 seconds.


100 metres at the Olympics, Finishing times, Top ten fastest Olympic times
Note:Florence Griffith-Joyner ran 10.54 (+3.0) and 10.70 (+2.6) in the finals and semifinals of the 100m at the 1988 Seoul Olympics, however, both were over the legal wind speed limit of +2.0m/s.


100 metres at the Olympics, Intercalated Games
The 1906 Intercalated Games were held in Athens and at the time were officially recognised as part of the Olympic Games series, with the intention being to hold a games in Greece in two-year intervals between the internationally held Olympics. However, this plan never came to fruition and the International Olympic Committee (IOC) later decided not to recognise these games as part of the official Olympic series. Some sports historians continue to treat the results of these games as part of the Olympic canon.


100 metres at the Olympics, Intercalated Games
At this event a men's 100 m was held and 1904 Olympic champion Archie Hahn of the United States won the race. Another American, Fay Moulton, was the runner-up and Australian Nigel Barker was the bronze medallist.


100 metres at the Olympics, Non-canonical Olympic events
In addition to the main 1900 Olympic men's 100 metres, two further 100 m events were held that year. A handicap race attracted 32 athletes from 10 countries and was won by Edmund Minahan, an American semi-finalist in the main 100 m competition, which had taken place five days earlier. A 100 m event for professionals only was held several weeks later. Four entrants are known and the winner was Edgar Bredin, a British former world record holder.


100 metres at the Olympics, Non-canonical Olympic events
A 100 m professionals handicap race is also believed to have been held in 1900. In 1904 a 100-yard dash handicap race was contested and an American, C. Hastedt, was the victor.


100 metres at the Olympics, Non-canonical Olympic events
These events are no longer considered part of the official Olympic history of the 100 m or the athletics programme in general. Consequently, medals from these races have not been assigned to nations on the all-time medal tables.


100 metres at the Olympics, Cultural impact
The 100 metres is typically considered one of the blue ribbon Olympic track and field events, and of the Olympic Games as a whole. The Olympic 100 m finals, particularly the men's, are among the most popular events from any sport at the Olympics – the 2012 Olympic men's 100 metres final was the most watched event at the London Games by British audiences (with 20 million television viewers) while in the United States that event was the third-most viewed Olympic clip.


100 metres at the Olympics, Cultural impact
The high-profile nature of 100 m Olympic finals in some countries has served to encourage participation in sport among the wider public, particularly in short sprinting. Successive generations of athletes cite previous 100 m Olympic champions as the reason for their entering the sport. The history of the event has had particular impact for African-American athletes: Jesse Owens' Olympic 100 m gold was an early example of a black American achieving success on an international stage while Wilma Rudolph's 1960 win inspired many black American women. Owens' 100 m victory at the 1936 Berlin Olympics (one of four gold medals he won over seven days at the games) helped challenge notions of white supremacy that were popular during that era.


100 metres at the Olympics, Cultural impact
1996 Olympic 100 metre champion Donovan Bailey from Canada had his billing as "World's Fastest Man" questioned by the American media, who instead promoted 1996 Olympic 200 metre and 400 metre champion Michael Johnson from the United States. After much sparring between the two athletes and media of their respective countries, an unsanctioned 150-metre race was held at the SkyDome in Toronto to settle the matter, with Bailey winning while Johnson pulled up injured, and they earned $1.5 million and $500,000, respectively.


100 metres at the Olympics, Cultural impact
The Olympic 100 metres has been covered by several film documentaries. Chariots of Fire, a 1981 historical drama focusing on Harold Abrahams' victory at the 1924 Paris Olympics, is among the most prominent.


100 metres at the Olympics, Cultural impact
The film won four Academy Awards, is often listed among polls for the best sports and Olympics films., and was ranked 19th in the British Film Institute's 100 Best British Films Wilma Rudolph was a central figure in The Grand Olympics (Italian: La grande olimpiade), an Academy-Award nominated documentary about the 1960 Rome Olympics, where Rudolph's 100 m feats earned her the nickname La Gazzella Negra (The Black Gazelle). The 1988 Olympic final, featuring Ben Johnson and Carl Lewis has been the topic of documentaries, including ESPN's "9.79*" from the 30 for 30 series, as well as non-fiction books, such as Richard Moore's The Dirtiest Race in History.


100 metres at the Olympics, Cultural impact
Across the sport of track and field, Olympic 100 m champions have often featured on Athlete of the Year lists. Carl Lewis (1984), Evelyn Ashford (1984), Florence Griffith-Joyner (1988) and Usain Bolt (2008) were chosen as Track & Field News Athlete of the Year in the year of their Olympic victories. Lewis, Griffith-Joyner, and Bolt were also awarded the title of IAAF World Athlete of the Year for their Olympic feats.


100 metres at the World Athletics Championships
The 100 metres at the World Championships in Athletics has been contested by both men and women since the inaugural edition in 1983. It is the second most prestigious 100 m title after the 100 metres at the Olympics. The competition format typically has two or three qualifying rounds leading to a final between eight athletes. Since 2011 a preliminary round has been held, where athletes who have not achieved the qualifying standard time compete to enter the first round proper.


100 metres at the World Athletics Championships
The championship records for the event are 9.58 seconds for men, set by Usain Bolt in 2009, and 10.70 seconds for women, set by Marion Jones in 1999. The men's world record has been broken or equalled at the competition three times: by Carl Lewis in 1987 and 1991, and by Usain Bolt in 2009. Ben Johnson beat Lewis in the 1987 final, but his win and record were subsequently rescinded after his admission to long-term steroid use. Lewis's mark, which equalled the standing record at the time, was never officially ratified by the IAAF as a world record. The women's world record has not yet been beaten at the championships.


100 metres at the World Athletics Championships
Shelly-Ann Fraser-Pryce is the most successful athlete of the event as the only person, male or female to win four titles. Carl Lewis, Maurice Greene and Usain Bolt are the most successful male athletes of the event, having each won three titles. Justin Gatlin has the most medals with 5, 2 gold and 3 silver. Merlene Ottey and Carmelita Jeter are the only other athletes to have claimed four medals in the history of the World Championships event.


100 metres at the World Athletics Championships
The United States is the most successful nation in the discipline, having won fifteen gold medals. Jamaica are a clear second with six gold medals. East Germany, with two, is the only other nation to have won multiple titles.


100 metres at the World Athletics Championships, Doping
Canada's Ben Johnson and Angella Taylor-Issajenko were both disqualified from the 1987 World Championships in Athletics for doping. Johnson was stripped of his 100 m gold, elevating Carl Lewis to world champion, while  Taylor-Issajenko finished fifth in the women's 100 m final.


100 metres at the World Athletics Championships, Doping
At the following edition in 1991, Irina Slyusar of the Soviet Union (a women's semi-finalist) was disqualified for doping. Eight years passed without incident in the 100 m before the double Nigerian doping disqualification of Innocent Asonze and Davidson Ezinwa in 1999.


100 metres at the World Athletics Championships, Doping
Tim Montgomery became the 100 m second medalist to be disqualified, losing his silver medal from the 2001 World Championships in Athletics. From the same event, Marion Jones later lost her silver medal for doping infractions, becoming the first female medalist to be stripped of a 100 m medal. Venolyn Clarke and Kelli White (a women's finalist) were also disqualified that year. The results of Dwain Chambers and Montgomery, fourth and fifth in 2003, were removed for doping. Two women's medalists were stripped of their honours for doping Kelli White lost the world title while Zhanna Block had her bronze medal removed. Block's times from the 2005 edition were also annulled. These disqualifications were a result of the BALCO scandal, which included many 100 m runners.

No doping offences were recorded at the 2007 World Championships 100 metres, but bans shortly returned, with Ruqaya Al-Ghasra being banned from the 2009 edition and a female trio of Inna Eftimova, Semoy Hackett and Norjannah Hafiszah Jamaludin being disqualified in 2011. The 2013 World Championships saw one elimination in Masoud Azizi.


100 metres at the World Athletics Championships, Doping
Among the men's world champions, only Donovan Bailey and Usain Bolt have not been implicated in doping during their careers; three-time champion Maurice Greene never failed a drug test, but admitting purchasing drugs on other athletes behalf.


100 metres freestyle
The 100 metres freestyle is often considered to be the highlight (blue riband event) of the sport of swimming, like 100 metres in the sport of Athletics.


100 metres freestyle
The first swimmer to break the one-minute barrier (long course) was Johnny Weissmuller, in 1922. The current world records holders are César Cielo (since 2009) and Sarah Sjöström (since 2017).


100 metres freestyle
Australian Dawn Fraser won the event a record three times at the Olympics, and she is the only woman to win it more than once. Four men, American Duke Kahanamoku, Weissmuller, Russian Alexander Popov, and Dutchman Pieter van den Hoogenband won the event at the Olympics twice. Popov was also world champion (held since 1973) three times.


100 metres hurdles
The 100 metres hurdles, or 100-meter hurdles, is a track and field event run mainly by women (the male counterpart is the 110 metres hurdles). For the race, ten hurdles of a height of 83.8 centimetres (33.0 in) are placed along a straight course of 100 metres (109.36 yd). The first hurdle is placed after a run-up of 13 metres from the starting line. The next 9 hurdles are set at a distance of 8.5 metres from each other, and the home stretch from the last hurdle to the finish line is 10.5 metres long.


100 metres hurdles
The hurdles are set up so that they will fall over if bumped into by the runner, but weighted so this is disadvantageous. Fallen hurdles do not count against runners provided that they do not run into them on purpose. Like the 100 metres sprint, the 100 m hurdles begins with athletes in starting blocks.


100 metres hurdles
The fastest 100 m hurdlers run the distance in a time of around 12.5 seconds. The world record set by Kendra Harrison stands at 12.20 seconds.


100 metres hurdles, History
The race started back in the 1830s in England where wooden barriers were placed along a 100 yard stretch. The hurdles event was included as part of the inaugural Women’s World Games in 1922, and made its first appearance in the Olympic Games in 1932 as 80m hurdles.


100 metres hurdles, History
Starting with the 1972 Summer Olympics, the women's race was lengthened to 100m hurdles.


100 metres hurdles, History
The hurdles sprint race has been run by women since the beginning of women's athletics, just after the end of World War I. The distances and hurdle heights varied widely in the beginning. While the men had zeroed in on the 110 m hurdles, the International Women's Sport Federation had registered records for eight different disciplines by 1926 (60 yards/75 cm height, 60 yards/61 cm, 65 yards/75 cm, 83 yards/75 cm, 100 yards/75 cm, 100 yards/61 cm, 120 yards/75 cm, 110 metres/75 cm). At the first Women's World Games in 1922, a 100 m hurdles race was run.


100 metres hurdles, History
From 1926 until 1968, the distance was 80 metres: women had to clear eight hurdles placed at a distance of 8 metres from each other and a height of 76.2 cm.


100 metres hurdles, History
Just like with the men's races, until 1935 no more than three hurdles could be knocked over, or the runner was disqualified, and records were only officially registered if the runner had cleared all her hurdles clean.


100 metres hurdles, History
In 1935, this rule was abandoned, and L-shaped hurdles were introduced that fell over forward easily and greatly reduced the risk of injury to the runner. Hurdles are weighted, so when properly set for the height (for women, closer to the fulcrum of the "L"), they serve as a consistent disadvantage to making contact with the barrier.


100 metres hurdles, History
The 80 m hurdles was on the list of women's sports demanded by the International Women's Sport Federation for the Olympic Summer Games in 1928, but wasn't included as an Olympic discipline until 1932. Starting with 1949, the 80 m hurdles was one of the disciplines included in the women's pentathlon.


100 metres hurdles, History
During the 1960s, some experimental races were run over a distance of 100 metres using hurdles with a height of 76.2 cm. During the 1968 Summer Olympics, a decision was made to introduce the 100 m hurdles from 1969, using hurdles with a height of 84 cm.


100 metres hurdles, History
The first international event in the 100 m hurdles occurred at the European Athletics Championships, which were won by Karin Balzer of the GDR.


100 metres hurdles, History
The modern 100 m race has an extra two hurdles compared to the 80 m race, which are higher and spaced slightly further apart. The home stretch is shorter by 1.5 m.


100 metres hurdles, History
As of 2021, no timeframe has been given by the IAAF for an increase to 110 metres, despite proposals to do so.


100 metres hurdles, Masters athletics
A version of the 100 metres hurdles is also used for 50- to 59-year-old men in Masters athletics. They run the same spacing as women, which coordinates with existing markings on most tracks, but run over 36-inch (0.915 m) hurdles. In the 60-69 age range, the spacings are changed. Women over age 40 and men over age 70 run 80 metre versions with different heights and spacings.

100 mexicanos dijeron
100 mexicanos dijeron (Spanish for One hundred Mexicans said), later rebranded to 100 mexicanos dijieron, is the Mexican version of the Goodson-Todman game show from the 1970s, Family Feud, produced in Mexico City by the Las Estrellas.


100 mexicanos dijeron
From 2001 to 2006 the show was hosted by Marco Antonio Regil and was called 100 Mexicanos Dijeron. In 2009 the program was revived this time hosted by "El Vítor" (Adrián Uribe) and titled El Vítor presenta 100 Mexicanos Dijieron. The newest season premiered on April 30, 2017 and was titled as 100 Mexicanos Dijieron.


100 mexicanos dijeron, Game Administration
The game is administered like the U.S. version of the game, with three single value questions, a double, and a triple value question. MX$5,000 is awarded for winning the game.


100 mexicanos dijeron, Game Administration
If neither family has three hundred points after four rounds, the fifth round is administered like the 1999-2003 US version (Anderson and first year of Karn) fourth round in that contestants will have the opportunity to pass or play, and the family loses control of the board on one strike.


100 mexicanos dijeron, Game Administration
During "El Vitor's" stint as host, episodes began to feature celebrities playing the main game on behalf of civilian families chosen from the audience. However, two members of the civilian family play "Dinero Rapdio" (Fast Money).


100 mexicanos dijeron, Game Administration
As of 2017, families of four compete in four rounds. The third question scores double points with only one "triple" question to follow. The runner-up family would receive MXN$10,000 (MXN$25,000 until 2018).


100 mexicanos dijeron, Dinero Rapido (Fast Money)
The winning family chooses two family members to play. One family member leaves the stage and is placed in an isolation booth, while the other is given fifteen seconds to answer five survey questions. If he or she can't think up an answer to any particular question, he or she may pass and come back to the question at the end, time permitting. The number of people giving each answer is then revealed answer by answer after the player is finished answering or time has expired. The player earns one point for each person that gave the same answer; at least two people must have given that answer for it to appear on the board.


100 mexicanos dijeron, Dinero Rapido (Fast Money)
Once all the points for the first player are tallied, the second family member comes back on stage and is given twenty seconds to answer the same five questions. The host will ask for another response should an answer be duplicated.


100 mexicanos dijeron, Dinero Rapido (Fast Money)
If one or both family members accumulate a total of 200 points or more, the family wins Dinero Rápido and MX$100,000. If the family members give the top answer for each question, they win a MX$25,000 bonus, regardless of the outcome. If only one family member named all five top answers, that bonus would double to MX$50,000.


100 mexicanos dijeron, Dinero Rapido (Fast Money)
On February 3, 2004, when the show was expanded to a full-hour format, an extra element was added to the second "Dinero Rápido", "La canasta de tentación" ("the basket of temptation"), a basket full of items, attached to each of which is a flag saying one of the following:


100 mexicanos dijeron, Dinero Rapido (Fast Money)
In 2017, the highest scoring family spun a wheel which contained amounts from MX$60,000 to MX$125,000 and winning Preguntas Rapidas won the amount spun. A family who lost Preguntas Rapidas would win MX$50,000. As of 2018, a member of the winning family chooses one of 12 spaces, each hiding a cash amount worth up to MX$50,000 and a loss would guarantee said family MX$20,000.


100 mexicanos dijeron, American nexus
100 mexicanos dijeron [or 100 mexicanos dijieron] ("Family Feud"), along with Trato hecho ("Let's Make a Deal"), are two classic 1970s game shows revived for Latin American audiences. Because of the close cultural connections with the US, many questions have American as well as Latino answers.


100 mexicanos dijeron, The board game
Due to the high popularity of this show, a board game of the same name has been created. It is sold in Mexico. The game contains 480 question cards, a 39x26 cm board, a pencil and a notepad.


100 mexicanos dijeron, The board game
Like in the show, two teams are formed and have to guess the answers given to the questions. The first team to reach 500 points wins. Unlike the TV show, the game does not include the final phase called Dinero Rápido ("Quick Cash", aka "Fast Money") where two players attempt to get up to 200 points answering five questions each. However, it hasn't been rare that families or parties playing attempt an imitation of the Dinero Rápido round.


100 mm air defense gun KS-19
100 mm air defense gun KS-19 (Russian: 100-мм зенитная пушка КС-19) was a Soviet anti-aircraft gun. Initially deployed aboard ships as the B-34 during the Second World War, a ground-mounted version was introduced into service after the war as the KS-19.


100 mm air defense gun KS-19
The KS-19 is a heavy towed anti aircraft gun that has largely disappeared from front line arsenals due to increased use of more effective surface-to-air missiles. Being a towed weapon an external form of mobility was required, usually an AT-S Medium or AT-T Heavy tracked artillery tractor. The 15 man crew were carried on the tractor along with ready use ammunition for the gun. Ammunition was loaded as a single round into the loading tray and a well trained crew could fire 15 rounds maximum per minute.


100 mm air defense gun KS-19
Anti Aircraft ammunition includes high explosive, high explosive fragmentation and fragmentation types. The KS-19's onboard sights can be used to engage air targets; however increased accuracy was achieved if used in conjunction with a fire control radar such as the SON 9 (NATO Reporting name 'Fire Can') and PUAZO-6/19 director.


100 mm air defense gun KS-19
As the KS-19 is a heavy calibre Anti- Aircraft gun it also has some utility in the ground role especially against armored targets. As a result of this two armor piecing rounds were produced: the AP-T (Armour Piercing-Tracer) and APC-T (Armour Piercing Capped-Tracer) with the AP-T round reportedly able to penetrate 185 mm of armor at 1000 m.


100 mm air defense gun KS-19
The KS-19 was used in action by communist forces in both Korea and Vietnam.


100 mm anti-tank gun M1977
The A407 100mm anti-tank gun M1977 is a Romanian rifled 100-mm anti-tank gun which serves as the main towed anti-tank gun of the Romanian Land Forces from 1975 until present. Versions of the M1977 gun were installed on main battle tanks (TR-77 and TR-85) and ship turrets on river monitors.


100 mm anti-tank gun M1977, History
The A407 100mm anti-tank gun was the first artillery piece designed in Romania after World War II. The first variant of the gun, the M1975 (M stands for Model) had a semi-automatic horizontal sliding wedge type breech lock. The second variant, M1977, had a more practical vertical sliding wedge breech block.


100 mm anti-tank gun M1977, History
The M1977 can be also used as a field gun at brigade level, as it has a maximum range of 20.6 kilometers. After 1992, the M1977 anti-tank guns were modernized with improved optical sights. The gun can be towed with the DAC 665T truck and has a maximum road speed of 60 km/h on road and 30 km/h off-road.


100 mm anti-tank gun T-12
2A19 or T-12  is a Soviet smoothbore 100-mm anti-tank gun, which served as the primary towed anti-tank artillery in the Soviet and Bulgarian armies from the early 1960s to the late 1980s.


100 mm anti-tank gun T-12, History
The T-12 entered service in 1961, replacing the BS-3 100 mm field gun. It was typically deployed in the anti-tank units of armoured and motor rifle regiments to protect flanks against counter-attacks during rapid advances.


100 mm anti-tank gun T-12, History
In 1970, it was replaced in production by the T-12A or MT-12 "Rapira", which features a new smoothbore gun, the 100 mm 2A29 gun, as well as a redesigned carriage and gun shield to protect the crew from machine gun fire and shell splinters. Thanks to the redesigned carriage, which has a bigger wheel base, the MT-12 can be towed by the MT-LB, at speeds up to 60 km/h on road or 25 km/h cross-country.


100 mm anti-tank gun T-12, History
The 2A29R "Ruta" or MT-12R is a version with a RLPK-1 radar for engaging targets in a poor visibility environment (smoke/fog). From 1981, the gun could fire laser beam-riding guided missiles 9M117 Kastet (weapon system 9K116) and carried the new designator 2A29K "Kastet" or MT-12K.


100 mm anti-tank gun T-12, History
The weapon was planned to be superseded by the 2A45 Sprut-B 125 mm smooth bore anti-tank gun. Modern western tanks' frontal armour protection is in excess of what can be penetrated by a 100 mm gun from anything but point-blank range – even using the most modern APFSDS round. For a tank that can manoeuvre to take advantage of the enemy's weaknesses this is less of a problem – but for a weapon that is primarily defensive, this is a serious problem. Today, the T-12 is applied mostly in the role of ordinary artillery, using FRAG-HE shells.


100 mm anti-tank gun T-12, History
In 2017, the Algerian military displayed a locally developed variant mounted on a Mercedes-Benz Zetros truck. It includes four stabilization legs to absorb firing impacts.


100 mm anti-tank gun T-12, Description
The gun requires a crew of six: commander, driver of the towing vehicle, gun layer, loader, and two ammunition crewmen. When the MT-LB is used as the transporter, 20 rounds are typically carried (10 APFSDS, 4 HE-Frag, 6 HEAT). Since the weapon is a smoothbore, all the ammunition is finned for accuracy during flight.


100 mm anti-tank gun T-12, Description
The standard equipment consists of the panoramic PG-1M sight for indirect fire, and an OP4M-40U telescope for direct fire. The APN-5-40 or APN-6-40 are used for direct fire by night.


100 mm anti-tank gun T-12, Description
The gun can be fitted with the LO-7 ski gear for travel across snow or swampy ground.


100 mm field gun M1944 (BS-3)
The 100 mm field gun M1944 (BS-3) (Russian: 100-мм полевая пушка обр. 1944 г. (БС-3)) was a Soviet 100 mm anti-tank and field gun. The gun was successfully employed in the late stages of World War II, and remained in service into the 1950s, being replaced in Soviet service by the T-12 antitank gun and the 85 mm antitank gun D-48 in 1955. The BS-3 was also sold to a number of other countries and in some of these countries the gun is still in service. A number of BS-3 pieces are still stored in Russian Ground Forces arsenals. Also, in 2012, at least 12 BS-3 guns are active with the 18th Machine Gun Artillery Division, located on the Kuril Islands, used as anti-ship and anti-landing guns.


100 mm field gun M1944 (BS-3), History
The BS-3 was based on the B-34 naval gun. The development team was led by V. G. Grabin.


100 mm field gun M1944 (BS-3), History
The gun was employed by light artillery brigades of tank armies (20 pieces along with 48 ZiS-3) and by corps artillery.


100 mm field gun M1944 (BS-3), History
In the Second World War the BS-3 was successfully used as a powerful anti-tank gun. It was capable of defeating any contemporary tank at long range, excluding the Tiger Ausf B: to destroy that heavy tank the gun needed to shoot at less than 1600 m from the target. The gun was capable of defeating the turret of Tiger II at a range of 800–1000 meters.


100 mm field gun M1944 (BS-3), History
The gun was also used as a field gun. Though in this role it was less powerful than the  122 mm A-19, as it fired a smaller round, the BS-3 was more mobile and had a higher rate of fire.


100 mm vz. 53
The 100 mm vz. 53 was a dual-purpose field gun and anti-tank gun designed and produced for the Czechoslovak Army during the 1950s.


100 mm vz. 53, History
When Czechoslovakia was created with the dissolution of Austro-Hungarian Empire after World War I it inherited a large and capable arms manufacturing industry. This allowed the new state to both design and produce its own weapons for domestic use and for export. After World War II this design and manufacturing experience allowed Czechoslovakia to not only produce Soviet designs under license but to produce equipment for its own use and for export to its Warsaw Pact allies. A consequence of its membership in the Warsaw Pact was that the military hardware it produced used Soviet caliber ammunition. This standardization was also pursued by NATO members, but with their own calibers of ammunition.


100 mm vz. 53, Design
Design and development of the vz. 53 began in 1948 at the Škoda Works in Pilsen under the company designation of A20. Problems with the design of ammunition lead to production being discontinued in 1950. It wasn't until 1953 that the problems were resolved and development resumed with designation vz.53. The vz.53 was designed to fill the same roles as the Soviet 100 mm field gun M1944 (BS-3) and used the same ammunition. Its performance was similar to that of the M1944 but since it was a unique design it had different dimensions. For night fighting it could be fitted with an infra-red sight.


100 mono Tobira
"100 mono Tobira" (100もの扉, lit. "100 Doors") is a song by Japanese singer-songwriters Rina Aiuchi and U-ka Saegusa. It was released on 14 June 2006 through Giza Studio, for the soundtrack of the Japanese animated television series Case Closed, for which the singers formed a special duo, Rina Aiuchi & U-ka Saegusa. The single reached number eight in Japan and has sold over 29,975 copies nationwide. The Japanese idol group, Sparkling Point were credited as the backing vocals for the song.


100 mph Club
The Champion Spark Plug 100 Mile an Hour Club was a group formed to honor drivers who completed the Indianapolis 500 at an average speed of 100 miles per hour or faster. It was formed in 1935, and continued to be recognized through 1969. It was sponsored by Champion Spark Plugs, and was the brainchild of M.C. deWitt, the company's advertising manager. During its heyday, it was considered one of the most prestigious honors in motorsports (the Indy car counterpart to NASCAR's famous Darlington Record Club), and membership was highly sought after by drivers.


100 mph Club
A total of 124 drivers were inducted as members, with 1930 winner Billy Arnold named the club's first member.


100 mph Club, History
The first driver to complete the Indianapolis 500 at an average speed of 100 mph was Pete DePaolo in 1925. However, Norman Batten drove 21 laps of relief (laps 106–127) while DePaolo had his hands bandaged due to blisters and bruises. Thus DePaolo did not accomplish the feat solo.


100 mph Club, History
Five years later in 1930, Billy Arnold won the race with an average speed of 100.488 mph. He was the second driver to complete the race in under five hours, but the first ever to do so without relief help.


100 mph Club, History
In 1934, M.C. deWitt, the advertising manager for Champion, had a conversation with driver Dave Evans. Evans had finished 6th in the 1934 Indianapolis 500. In doing so, Evans had become the twelfth driver in history to complete the full 500 miles solo, at an average speed of over 100 mph. Immediately deWitt envisioned an idea to create an honorary "club" for the drivers who had accomplished the noteworthy feat. In 1935, the Champion Spark Plugs 100 mph Club was born.


100 mph Club, History
The inaugural class would consist of the 12 drivers who had accomplished the feat thus far. The first member retroactively being Billy Arnold, along with Fred Frame, Howdy Wilcox II, Cliff Bergere, Bob Carey, Russ Snowberger, Louis Meyer, Chet Gardner, Wilbur Shaw, Lou Moore, Stubby Stubblefield, and Dave Evans. An annual banquet would be held in the drivers' honor, and each inductee would receive a leather jacket. Carey and Stubblefield were deceased, and Arnold did not attend, but all of the other nine living members were present at the first banquet.


100 mph Club, Membership qualifications
The requirements to qualify for the 100 mph Club were fairly straightforward. A driver was required to complete the Indianapolis 500 at an average speed of 100 mph or faster, driving the entire race without any relief help. It was permissible to be accompanied by a riding mechanic. However, the period in which riding mechanics were utilized at Indianapolis overlapped only briefly from when the club was formed.


100 mph Club, Membership qualifications
The 100 mph average speed equated to finishing the race in five hours or less. The driver was not required to win the race, but a strict requirement was to complete the full 500 miles (200 laps). Rain-shortened races, or drivers that were flagged off the track before completing all 200 laps (even if their average speed was over 100 mph at the time) would not qualify.


100 mph Club, Membership qualifications
Drivers were inducted for lifetime memberships, but drivers were separately honored each time they accomplished the feat. Many drivers broke the 100 mph barrier multiple times during the career. Ted Horn accomplished the feat a record total of eight times in his career. Each subsequent membership was rewarded with being seated at the head table during the next annual banquet.


100 mph Club, Membership qualifications
Prior to the 1960s, the drivers were permitted ample time to complete the full 500 mile distance, even if it meant remaining on the track for several minutes or over an hour after the winner crossed the finish line. In the very early years, completing the full 500 miles was even a requirement to receive any prize money. For a time, it was the norm for officials to wait until at least 10-12 cars completed the 500 miles before waving the cars off the track. However, that was not a hard-and-fast rule. Officials often just used judgement to decide when it prudent to stop. A total of 16 cars went the distance in 1959, while only five did so in 1938. In 1940, only the top three were permitted to finish, due to a rain shower.


100 mph Club, Membership qualifications
The honor of joining the prestigious 100 mph Club was considered motivation to continue racing, even if the chance to win the race had already gone away. In most cases, several cars would complete the distance, and numerous drivers might be added to the Club annually.


100 mph Club, Champion Highway Safety Program
Around 1954, Champion formed as part of their public relations efforts, a Driver's education program geared towards teenagers and young adults. The Champion Highway Safety Program traveled around the country giving presentations at high schools and military bases about driving safety tips. For many years, a team of drivers from the 100 mph Club were used to give the lectures, and some were used in Educational films.


100 mph Club, Champion Highway Safety Program
The lectures were popular and well-received, and were usually sponsored by a local newspaper or radio station. The appearances were also used as promotional tool for automobile racing, and offered the drivers work during the off-season.


100 mph Club, Demise
In 1964, when the race started airing live on MCA closed-circuit television, the rules were changed which limited the time drivers were allotted to finish the race once the winner crossed the finish line. Roughly five minutes were allowed for the other cars on the track to complete the 200 laps. This had the effect of substantially limiting the chances of joining the 100 mph Club, and only a handful of drivers earned the honor after 1964.


100 mph Club, Demise
Also perhaps contributing to the club's demise was the evolving times. By the mid-1960s, speeds at Indy had risen considerably since the club's formation - and were poised to rise substantially over the next few years. Covering the full 500 miles at an average speed of 100 mph was nay considered a noteworthy accomplishment any longer. Most winners were finishing the race with as much as an hour and a half to spare to fulfill the 100 mph Club's qualifications. Apropos to that, membership in the drivers' eyes was still highly coveted.


100 mph Club, Demise
In 1964, Autolite created the "Pacemakers Club," which recognized drivers who had led at least one lap during the race. It began to rise in stature and popularity, and became a more period-relevant "club," associated with the Indianapolis 500. In its favor, it was not linked to changes in equipment, conditions, or perceived obsolete speed milestones.


100 mph Club, Demise
During the 1969 race, no new members were inducted into the 100 mph Club, since all four drivers who completed the 500 miles that year were already part of the club. In 1970, Dick McGeorge, Champion's public relations representative, retired from his position. McGeorge was considered the key fixture in organizing the club, dating back to 1946. He died in 1971, and the 100 mph Club quietly folded. In retrospect, the 1968 inductees (led by race winner Bobby Unser) would be the final names added to the membership.


100 mph Club, Demise, Al Unser
One of the more notable omissions from the 100 mph Club was Al Unser Sr. He first arrived at Indianapolis in 1965, finishing 9th, flagged after 196 laps. He crashed out in 1966, but in 1967, he was running second in the waning laps. As leader A. J. Foyt was coming out of turn four to take the checkered flag, a crash occurred on the front stretch. Foyt weaved his way through the wreck to win, but officials immediately thereafter put out the red flag to stop the race. Al Unser was about a lap and a half away from the finish line when he was flagged off and was officially credited with only 198 laps in the final scoring.


100 mph Club, Demise, Al Unser
Unser crashed out of the 1968 race. His brother Bobby won, and incidentally joined the 100 mph Club for himself. Al Unser missed the 1969 race due to a broken leg suffered in a motorcycle crash earlier in the month. In 1970, he came back to win the race in dominating fashion. His average speed of 155.749 mph was well over the requirement to be invited into the club, and he was expected by all to be honored as the next member. However, after McGeorge's retirement, and subsequent passing, the 1971 banquet never happened. The club was quietly abandoned and membership was closed without Al Unser ever being officially inducted.


100 mph Club, Demise, Al Unser
Incidentally, following the demise of the 100 mph Club, Al Unser would go on to complete the full 500 miles seven times (including four wins), all at better than a 100 mph average.


100 mph Club, Post award
From 1970 to 2016, a total of 108 additional drivers have unofficially joined the 100 mph Club. Although no official subcategories have ever been created, a total of 98 of them made it into a faster "150 mph Club."


100 mph Club, Post award
A total of 33 drivers have joined the very exclusive "185 mph Club". They are led by Tony Kanaan, who won the fastest 500 in 2013. Two additional drivers, Rick Mears and Michael Andretti, managed to break the 175 mph barrier from the 1991 race.


100 mph Club, Post award
During the late 1980s and early 1990s, a separate award was created called the Marlboro 500 Mile Club. Sponsored by Marlboro, it was a cash prize of $75,000 split amongst the drivers who completed the full 500 miles each year.

100 of the World's Worst Invasive Alien Species
100 of the World's Worst Invasive Alien Species is a list of invasive species compiled by the Global Invasive Species Database in 2014. The IUCN Invasive Species Specialist Group (ISSG), which maintains the list, acknowledges that it is "very difficult to identify 100 invasive species from around the world that really are 'worse' than any others."


100 of the World's Worst Invasive Alien Species, Criteria for inclusion
Two criteria were used in selecting items for the list:


100 of the World's Worst Invasive Alien Species, Criteria for inclusion
According to the ISSG, "only one species from each genus was selected."


100 percent corner
The 100 percent corner is the busiest area in a city. Often it is a crossroads of several major streets, and the place with the highest land value and/or where grid plan numbering is based upon. The term is also used for the place for ideal real estate projects, sometimes considered the intersection of two highways in a suburban area. The terms "hundred percent location", "hundred percent corner", or "peak land value intersection" may also be used.


100 percent corner
The 100 percent corner is used in research as part of a method to determine a city's downtown area, by measuring a radius (e.g. one mile) from the central intersection.


100 point check
The 100 point check is a personal identification system adopted by the Australian Government to combat  financial transaction fraud by individuals and companies, enacted by the Financial Transactions Reports Act (1988) (FTR Act), which established the Australian Transaction Reports and Analysis Centre (AUSTRAC) and which continued in existence under the Anti- Money Laundering and Counter-Terrorism Financing Act 2006.


100 point check
The 100 point system applies to individuals opening new financial accounts in Australia, including bank accounts or betting accounts. Points are allocated to the types of documentary proof of identity that the person can produce, and they must have at least 100 points of identification to be able to operate an account. The system now also applies to the establishment of a number of official identity documents, such as an Australian passport and driving licence.


100 point check
Additionally, 100 point checking also applies in superannuation. Members are required to provide 100 points of ID when applying to transfer their accumulation funds (receiving monies) to a pension-based fund (paying monies). "Reporting entities" are required to identify their customers using the 100 point check system. Accounts may be opened, but can only be operated (i.e. withdrawals made) by an identified customer; and an unidentified customer is blocked from making withdrawals. Generally, identification can be transferred from one account to another, so that for instance a person once identified does not need to produce documents again when opening a second account at the same institution.


100 point check
An issue for many Australian organisations is the capture of credit card primary account numbers (PANs), referred to below under the 25 points section as credit cards or EFTPOS cards. This practice is not compliant with the Payment Card Industry Data Security Standard and must be removed from all 100 point check forms.


100 prisoners problem
The 100 prisoners problem is a mathematical problem in probability theory and combinatorics. In this problem, 100 numbered prisoners must find their own numbers in one of 100 drawers in order to survive. The rules state that each prisoner may open only 50 drawers and cannot communicate with other prisoners. At first glance, the situation appears hopeless, but a clever strategy offers the prisoners a realistic chance of survival. Danish computer scientist Peter Bro Miltersen first proposed the problem in 2003.


100 prisoners problem, Problem
The 100 prisoners problem has different renditions in the literature. The following version is by Philippe Flajolet and Robert Sedgewick:


100 prisoners problem, Problem
If every prisoner selects 50 drawers at random, the probability that a single prisoner finds his number is 50%. Therefore, the probability that all prisoners find their numbers is the product of the single probabilities, which is (1/2)100 ≈ 0.0000000000000000000000000000008, a vanishingly small number. The situation appears hopeless.


100 prisoners problem, Solution, Strategy
Surprisingly, there is a strategy that provides a survival probability of more than 30%. The key to success is that the prisoners do not have to decide beforehand which drawers to open. Each prisoner can use the information gained from the contents of every drawer he already opened to help decide which one to open next. Another important observation is that this way the success of one prisoner is not independent of the success of the other prisoners, because they all depend on the way the numbers are distributed.


100 prisoners problem, Solution, Strategy
To describe the strategy, not only the prisoners, but also the drawers are numbered from 1 to 100, for example row by row starting with the top left drawer. The strategy is now as follows:


100 prisoners problem, Solution, Strategy
By starting with his own number, the prisoner guarantees he is on a sequence of boxes containing his number. The only question is whether this sequence is longer than 50 boxes.


100 prisoners problem, Solution, Examples
The reason this is a promising strategy is illustrated with the following example using 8 prisoners and drawers, whereby each prisoner may open 4 drawers. The prison director has distributed the prisoners' numbers into the drawers in the following fashion:


100 prisoners problem, Solution, Examples
In this case, all prisoners find their numbers. This is, however, not always the case. For example, the small change to the numbers of swapping drawers 5 and 8 would cause prisoner 1 to fail after opening 1, 7, 5, and 2 (and not finding his own number):
