There are a few theories as to what causes this pain; 1  Irritation caused by blood and fluid when the egg is released. The blood and fluid can irritate tissues in the abdominal lining. 2  Bruising is caused during ovulation when the ovarian wall ruptures. 3  Fallopian tube muscle contractions cause discomfort.
5k runners always have a very wide range of times. For a 40 year old, some are able to run around 17-18 minutes, then there are the walkers who do it in around 40-45 minutes. â¦ The overall average for a 40 year old male on a 5k course is between 22 and 25 minutes.or 50-year-old male runners (who are pretty good), probably 6-9 minutes. For the average runner, m â¦ aybe 8-11 minutes. And for just a random guy off the street, most likely between 10 and 15 minutes.
Another major factor with 5km pace running is that it must not be forgotten that the race is now 12 consecutive laps at 61.5 secs per 400m, p1us 200 metres. An athlete who does 13 x 400m in 61.5 secs and jogs 400m recovery (2-3 mins), is not getting used to sustained running effort.f you want to run 15 mins for 5km, you have to know thatâs 72 secs / 400m and get used to it for spells lasting 3-5 minutesâ duration with short rest. Also, you will realise that a good 3km time aids the realisation of a good 5km. For example. Liz McColgan ran 8:34.80 for 3km in 1989, thatâs 69 secs / 400m.
