That urge you have to run after an animal until it dies may lie in your genes!

This article explains that proponents of the Endurance Running Hypothesis

believe that being able to run for extended lengths of time is an adapted trait, most likely for obtaining food, and was the catalyst that forced Homo erectus to evolve from its apelike ancestors. Over time, the survival of the swift-footed shaped the anatomy of modern humans, giving us a body that is difficult to explain absent a marathoning past.

Apparently, the ability to run long distances became an advantage, allowing us to run long distances, chasing animals who, though much quicker in short sprint races, don't have the ability to properly 'pant' off the heat that results from long distance running. This hypothesis is supported by the observed practice employed by some native groups, running game until their hooves fall off.
