Usain Bolt is the fastest recorded human sprinter. His top speed during a 100-meter race has been measured at approximately 44.72 kilometers per hour (27.8 miles per hour)

. Bolt set the world record for the 100-meter sprint at 9.58 seconds in 2009. During this record run, his average speed was about 37.58 kilometers per hour (23.35 miles per hour), but his peak speed reached nearly 44 kilometers per hour (27.33 mph) around the 67-meter mark

. This peak speed is faster than typical traffic speeds in major U.S. cities and is extraordinary given that he started from a standstill and had to accelerate to reach it. In summary, Usain Bolt can run at a top speed close to 44.7 km/h (27.8 mph) during his fastest 100m sprints, making him the fastest human ever recorded in terms of running speed
