Usain Bolt — 9.58 seconds

Jamaican sprinter Usain Bolt set the 100m world record of 9.58 seconds at the 2009 Berlin World Championships — a record that has stood for 16 years and which biomechanists suggest may stand for decades more. He also holds the 200m world record (19.19s) and won eight Olympic gold medals across Beijing, London, and Rio, making him the most decorated sprinter in history.
