In the book Born to Run, the author, Christopher McDougall, refers to the world’s greatest ultra-runners, the Mexican Indian tribe known as the Tarahumara, as great athletes–not as great runners. Far from simply being good at covering ground, the Tarahumara are described as agile, strong, and well-coordinated. They manage to be all these things while still maintaining the ability to run hundreds of miles non-stop. Basically, they have the superhuman endurance of running specialists, without incurring the usual penalties of doing so.
