Whatever these Stone Age folk were doing, the largest of them achieved a running speed of perhaps 12 miles per hour, comparable to that of a fit recreational runner today,

Hmmm.....a marathon is 26 miles...at 12 miles/hour....or 5 minutes a mile

A 2:10 marathon (approximately & rounded)

Pretty good for a "recreational runner today"!

Methinks they need another working hypo here.

Who said they ran a marathon? Don't you think these ancient people were in pretty good physical shape? They probably used running as a major part of their hunting.

Not too many years ago I could run a 5 minute mile (although not now) and I'm about 6 ft. But I never could run 26 of them at a time. I only ever ran 2 marathons and the best I did was slightly less than 8 minutes. Needless to say I didn't finish anywhere the top :)

Achieving a certain speed is not the same as maintaining the same speed.

They never claimed the "Stone Age folk" could maintain 12 miles per hour for 26 miles.
