Did Our Ancestors Become Bipedal So They Could Throw?

Horses (and various ruminants) are a bad example because they need a relatively big mass of fiber in their digestive tracts. Can't do that on two legs. Still, their fore legs are considerably lighter and contribute relatively little to forward motion.

For that matter, a human can run down a horse. Some Africans still do that with zebras. Cats can't do that.

And no, "pumping" arms around is not really a necessity.

Humans win occasionally.

Again, Humans have done this as a hunting strategy for at least as long as there is H. sapiens sapiens. Pick an individual animal, run after it until it collapses.

I guess the horses they hunted weren't as well trained, bred and fed as those in sports competitions. Wild horses in general evolved to run occasionally over relatively short distances.

Yeah, I wasn't posting it as contrary evidence. Note the part where humans do win.

Several humans working together in familiar territory would likely be able to start an animal sprinting several times in fairly rapid succession and avoid the marathon.
