Was is David Attenborough's "Planet Earth"? There was a bit about a tribe that hunt antelope or some other kind of herd animal. After separating one from the herd, the human eventually "outruns" it. Not in speed but just tenacity, endurance — the animal eventually collapses.

Blew my mind that we could do that.
