They aren't though, unless you start adding specifically tailored constraints like the run should happen in a very hot place.
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).
