how fast can a human run in km/h
Footspeed The record was 44.72 km/h (27.8 mph), seen during the final 100 meters sprint of the World Championships in Berlin on 16 August 2009 by Usain Bolt.[4] (Bolt's average speed over the course of this race was 37.58 km/h or 23.35 mph.)[5] Maximum human sprint speed is strikingly slower than that of many animals. Compared to other land animals, humans are exceptionally capable of endurance, but incapable of great speed.[6] For example, cheetahs can attain short bursts of speed well over 100 km/h (62 mph),[7] the American quarter horse has topped 88 km/h (55 mph),[8] greyhounds can reach 70 km/h (43 mph), and the Mongolian wild ass has been measured at 64 km/h (40 mph).[9] Even the domestic cat may reach 48 km/h (30 mph).[9]
