Yes, but it is all just speculation. And when you compare it to how poorly our bodies handles running now I would say it is a weak argument.

Also the "we can run the prey tired" argument clashes with the observations of hunter gatherers where large animals plays a very small role in day to day diet.

Also there is a very large opportunity cost for running after large pray.

Imagine 5-10 hunters running after a big pray, and not catching it. Now they have been running a half marathon. They might be far from water. They have expended a lot of energy and will be hungry and tired and will have to walk home to camp. With nothing to eat.

I think there is a good reason that hunting aminal usually just sprints for short durations. The other approach is simply too risky.

Nope. Walking it is.
