Average Speed. If you take the average speed of the current world 100 m record (Bolt's 9.58 s), you get about 10.44 meters/sec (23.35 miles/hr, 37.58 km/hr). However, if you were to record instantaneous speed at different points throughout the race, the runner would reach a maximum speed much greater than this.
In 1983 Mike Boit of Kenya ran a mile in 3:28.36. As far as I know, no one has ever covered the distance faster. This was on a downhill road course so it isn't recognized by IAAF but it's still the fastest mile ever run by a human. The world record in the mile run is the best mark set by a male or female runner in the middle-distance track and field event.
