Can a human run 30 mph?

Humans could perhaps run as fast 40 mph, a new study suggests. Such a feat would leave in the dust the world’s fastest runner, Usain Bolt, who has clocked nearly 28 mph in the 100-meter sprint. The new findings come after researchers took a new look at the factors that limit human speed.

What is Usain Bolt’s average mph?

23.35 mph
The record was 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint of the [[2009 World Championships in Athletics – Men’s 16 August 2009 by Usain Bolt. (Bolt’s average speed over the course of this race was 37.58 km/h or 23.35 mph.)
