there is more evidence of our long distance running prowess if you look at energy expenditure vs speed plots. we are far from fast in a maximum velocity sense but if you look across phyla from horses to humans to cheetahs you see that we have a huge advantage in "trotting" speeds. we walk with a fairly low energy cost but sprinting is much much more taxing to us then horses or cheetahs. at a trotting speed though, which is about what youd get if you were a true long distance runner, we are far and away more efficient then most other animals. Hyenas and wild dogs have a similar advantage. The african bushmen that track animals over days of terrain finally succeed due to this evolutionary advantage in efficiency. more proof of this is if you actually look at animals that try to trot or jog, horses have to be trained to do so simply because its just so out of there natural condition to do so.
