In MPH what is the fastest a human has ever run? |
Though Bob Hayes, in 1964, ran his leg of the 4x100m relay in 8.50 seconds.
During Usain Bolt's World record 100m sprint (9.58) at the 2009 Athletic Championships in Berlin, Usain covered Bolt reaches his top speed of 12.27 m/s or 27.45 miles per hour at the 65 meter mark.
For a biomechanical breakdown of Bolt's 9.58 WR, see:
