>>1598575You underestimate dogs. Look at the ones who are bred and trained for it, I run dogs on a hilly sheep and cattle farm, they can run up and down the place at 20-30mph all day following the motorbike and heading up and down steep slopes to retrieve stock. Then they do it all again tomorrow. Could probably run rings around a wolf pack also, probably any animal on earth on this kind of terrain, even 4 minute mile runners or ultra marathon runners aren't going to beat them up and down hillsides all week, even a horse can't climb like them.
>>1606935The world record is 4.40 pace and of course done on flat ground. The average marathon runner does it half as quickly as that and the average man doesn't even run a marathon.
