Human beings the best long distance runners on the planet. I think that's awesome as well ;)
A trained horse can cover 100+ miles per day with a rider, a husky can run 100+ miles in a sledge, and they will probably outpace humans. Not to mention that only a tiny fraction of humans can even finish a marathon, which is no big deal for most wolves or horses.
And camels and maybe ostriches will probably outrun us in hot climate as well (but that I didn't check).
Depends on the time constraints - I think a large percentage people can finish a marathon within 12 hours, even more if you allow up to 16 hours.
