Men's 100 metres world record progression
List of world records for men's 100m sprint
IAAF-ratified world record progression for the men's 100 m. In 1977 the IAAF began requiring fully automatic timing, accounting for both the increase in measured times and the decrease in measurement uncertainty.
The first record in the 100 metres for men (athletics) was recognised by the International Amateur Athletics Federation, now known as World Athletics, in 1912.
As of 21 June 2011[update], the IAAF had ratified 67 records in the event, not including rescinded records.[1]
