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.
Where once the maximum top speed of a human being was thought to be around 28 mph, a new study suggests that a trained runner could achieve speeds of 40 mph, or perhaps even more. If true, it could mean that human-powered mobility might be more practical than previously thought.
