The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by Usain Bolt. [4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.)

[13] 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. [14]

Due to a tailwind helping to enhance the speed of the athlete in events like certain sprint races (100 and 200 metres), 100/110 metres hurdles, the triple jump and the long jump, there is a limit to how much wind assistance the athlete may compete under if the performance is to establish a record.
