Usually, it is seen that most animals easily outrun humans. However, it is true only for short distances. When it comes to long distances and endurance running, humans can outrun almost every other animal on the planet. It is an evolutionary trait, that developed when prehistoric humans hunted animals by simply outrunning them until they stopped due to exhaustion.

This sweating and virtually hairless body give humans the edge over other animals in endurance running.
The only animal to outrun humans is horses.
