How Fast Is Average Human Sprint?

A healthy adult can sprint at 5-6 m/s. The body's tendons store elastic energy like springs during the running cycle, returning it on push-off. Even so, a domestic cat at full sprint would still beat us.

A domestic cat at full sprint can outrun any human who has ever lived — including Usain Bolt.

• Still slower than a domestic cat
• 4× faster than walking
