Men's 100 metres world record progression

Unofficial progression before the IAAF

10.8	Luther Cary	United States|1891GBRBELGBRGBRSWESWESWE IAAF record progression Ratified Not ratified Ratified but later rescinded "Wind" in these tables refers to wind assistance, the velocity of the wind parallel to the runner - positive values are from the starting line towards the finish line, negative are from the finish line towards the starting line, 0 is no wind in either direction, and all values are measured in metres per second. Any wind perpendicular to the runners is ignored and not listed. "Auto" refers to automatic timing, and for the purposes of these lists, indicates auto times which were either also taken for hand-timed records, or were rounded to the tenth or hundredth of a second for the official record time. Records 1912–1976 Time Wind Auto Athlete Nationality Location of race Date Ref 10.6 Donald Lippincott United States|1912 Records since 1977 Since 1975, the IAAF has accepted separate automatically electronically timed records for events up to 400 metres. Starting on January 1, 1977, the IAAF has required fully automatic timing to the hundredth of a second for these events. Jim Hines' October 1968 Olympic gold medal run was the fastest recorded fully electronic 100 metre race up to that date, at 9.95 seconds. Track and Field News has compiled an unofficial list of automatically timed records starting with the 1964 Olympics and Bob Hayes' gold medal performance there. Those marks are included in the progression. The event is linked on some of the dates.

However, high altitude can significantly assist sprint performances. One estimate suggests times in the 200 m sprint can be assisted by between 0.09s and 0.14s with the maximum allowable tailing wind of 2.0 m/s, and gain 0.3s at altitudes over 2000m. For this reason, unofficial low-altitude record lists have been compiled. After the IAAF started to recognise only electronic times in 1977, the then-current record and subsequent record were both set at altitude. It was not until 1987 that the world record was equalled or surpassed by a low-altitude performance. The following progression of low-altitude records therefore starts with Hines's low-altitude "record" when the IAAF started to recognise only electronic timing in 1977, and continues to Lewis's low-altitude performance that equalled the high-altitude world record in 1987.
