Usain Bolt reached an estimated top speed of about 44.72 km/h (27.8 mph) during his 100 m world record run. The record was measured with fully automatic timing and ratified by World Athletics, the global governing body for track and field.
How Records Are Verified
World Athletics verifies records using calibrated timing systems, wind measurement, and drug testing. Athletes must comply with anti-doping rules and event regulations for a performance to be recognized as an official world record.
