My favorite book lately is definitely "Born to Run", by Christopher McDougall. It's basically an anthropological study on how crucial the ability to run long distances efficiently has been for the development of the modern Human. Believe me, the book is a lot more interesting than that; the book revolves around an Indigenous Tribe of Mexico, the Tarahumara, known for their superhuman abilities to run hundreds of miles for days on end. While studying how the Tarahumara can seemingly run hundreds of miles on flimsy homemade sandals without injury, the Author soon becomes concerned about their plight of extreme poverty and encroaching drug violence on their territory. With the help of an interesting cast of characters the author meets along the way (most notably Caballo Blanco and Scott Jurek), a 50-mile race is held deep in the Copper Canyons of Mexico, pitting the best Ultra-Marathoner's of the United States against the legendary Tarahumara runners, all to raise awareness to their hardships. In between all of this, the author weaves in the anthropology bits and makes a passionate case on why everyone should run because we’re all, as the title suggest, Born to Run!
