According to the Guiness Book of World Records, the fastest a human has run is 200 m in 19.32 seconds by Michael Johnson (US) Atlanta, Georgia, July 21, 1996.
Astronauts are by far the fastest traveling humans with the earth as a stationary reference point. One might think the Apollo missions to the moon are the fastest traveling humans, but the speed of that spacecraft was only about 6,300 miles per hour. In fact, an orbiting space shuttle is much faster at 17,600 miles per hour. This is the fastest any man has reached. Although it seems very fast to us, this speed is 0.026% of the speed of light. For unassisted speed using Usain Bolt's time in the 100 meter, his top speed is 23.3 miles per hour (10.4 m/s).
