The legal wind assistance (blowing from the competitor's back) for the 100 meter dash, 200 meter dash, long jump, triple jump, and hurdle sprints is 2 meters per second. This works out to about 4.5 MPH. Tyson Gay's 9.68 was run with a wind assistance of 4 meters per second, twice the allowable limit. This is why his time will not be recognized as a world record. According to the Academy for Sports Excellence, the different in a 100 meter dash time can be as much as 0.15 seconds when run with wind assistance of 2 meters per second compared to when run with calm winds.
