Born to Run: A Hidden Tribe, Superathletes, and the Greatest Race the World Has Never Seen

A couple of really interesting observations out of this book:
* Nike knows it’s been wrecking our feet for the last 30 years with additional cushioning. Now it’s introduced shoes that have less support, which should technically be better for your feet.
* Your feet are highly sensitive instruments, adjusting how they hit the ground based on the firmness of the initial touch.
* Homo sapiens beat out Neanderthals because we evolved to run. We engaged in persistence hunting, running our meat down. Not fast, but endurance counts. Our ability to sweat away our heat keeps our engines cooled, while our prey has to release heat through breathing.
McDougall does a nice job interweaving his personal story of running with the Tarahumara Indians in Copper Canyon (Mexico), along with science, evolution, ultramarathoning.
