Men's 100 metres world record progression The first record in the 100 metres for men (athletics) was recognised by the International Amateur Athletics Federation, now known as the International Association of Athletics Federations, in 1912. The record now is 9.58 seconds which was run by Usain Bolt.
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 cm are placed along a straight course of 100 m . 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. 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.
