The fastest animal on land is the cheetah, but only over a short distance. If the prey runs fast or twists and turns enough, the cheetah has to stop or risk overheating. Even a lion chasing an antelope would give up after a certain time or distance has been reached. But, in the Kalahari Desert, the indigenous Bushmen have been known (on a BBC documentary) to have pursued an eland antelope buck for several days. Eventually the eland was too exhausted to go on, when the bushmen killed it. It fed the bushman's village for several days. So, in conclusion, a cheetah may be fast, but it is the stamina of the Kalahari Bushmen, and the stamina of a well trained, modern day marathon runner that proves stamina is often better than speed (sorry, pun coming in!) - in the long run.
