They are mistaking walking for running. Humans are built to WALK long distances – far enough to walk just about anything else to exhaustion. Running is a very different gait. We can do some running at different paces, but the sprint is the most important.

That article argues that human beings are _evolved_ to run long distances. There is some interesting talk about the concept of ‘persistance hunting’. That concept posits that early hunter gatherers primary hunting strategy was to hunt prey by chasing them over long periods until the prey dropped down out of exhaustion.

There also other anecdotes about modern day hunter-gatherer populations who regularly run long distance, and how healthy they are.

This article uses the same evolutionary premise of the primal blueprint to recommend an activity patterns which totally contradict the activity patterns recommended by the primal blueprint. I think it would be greatly educative and entertaining to investigate this dichotomy.

Happy easter!
