We evolved to be really good long-distance runners. One of the adaptations that helps us in this regard is less thick body-hair. We have heat regulation options that are available to few other animals.
That is why, over a long distance, there are few, if any animals, that can keep up with humans.
I for one, am a very intelligent crappy long distance runner. All my time in the Army still couldn't get me to be good at it.
