In what year did Willie Williams set the 100 metres world record that was recorded by the International Association of Athletics Federations?
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.
Men's 400 metres world record progression The first world record in the 400 m for men (athletics) was recognized by the International Amateur Athletics Federation, now known as the International Association of Athletics Federations, in 1912. The IAAF ratified Charles Reidpath's 48.2 performance set at that year's Stockholm Olympics as a world record, but it also recognized the superior mark over 440 yards (402.34 metres) run by Maxie Long in 1900 as a world record.
