Now the NYT has taken up the paradox of if humans are made for running long distances then why are there so many injuries?

Running on only artificial surfaces and in high-tech shoes can change the biomechanics of running, increasing the risks of injury.
What’s the solution? Slower, easier training over a long period would most likely help; so would brief walk breaks, which mimic the behavior of the persistence hunter. And running on a variety of surfaces and in simpler shoes with less cushioning can restore natural running form.
