Long-distance running, often known as endurance running, is a kind of continuous running that takes place over distances of at least three kilometres (1.9 mi). Physiologically, it is mostly aerobic in nature, and it requires both physical stamina and mental power.
Humans are among the best-adapted animals for long-distance running, and they are especially well-suited for it among primates. The endurance running theory proposes that the evolution of running endurance in the genus Homo occurred as a result of the benefits of travelling over vast distances for scavenging chances and the ability to engage in persistent hunting. Besides migratory ungulates and a small number of terrestrial carnivores like bears, dogs, wolves, and hyenas, the ability to sprint over long distances is also seen in a variety of other animals.
