Gunder HÃ¤gg (right) defeats Arne Andersson with a world record for the mile of 4:06.2 min in Gothenburg in 1942. The mile run (1,760 yards or exactly 1,609.344 metres) is a middle-distance foot race. The history of the mile run event began in England, where it was used as a distance for gambling races. It survived track and field's switch to metric distances in the 1900s and retained its popularity, with the chase for the four-minute mile in the 1950s a high point for the race.
