If it were me, I would've told my buddies to start building a fence for next time while I was out hunting it down. Also dogs and horses could have helped with the hunt. How is he meant to carry the carcass back? Does he light a fire to signal to the others to help him? What happens if tigers smell the blood or no one reaches him in time, or a pack of hyenas are following the hunter? Most of the time, a lot of the hunt was reconnaissance (endurance yes, jogging no.) Large groups of people jogging frequently for long groups of time doesn't seem right, perhaps in parts of Africa (eg Kenya) jogging has become part of society and remains fun. Bipedalism has other benefits besides endurance: vision, climbing, reach, sitting, freeing up hands, inducing fear. People going on a 10km run every weekend, on concrete, in a polluted city, with a hunched back is just wrong. Just because you can jog, doesn't mean you must.
