TED-Ed

Christopher McDougall explores the mysteries of the human desire to run. How did running help early humans survive -- and what urges from our ancient ancestors spur us on today? McDougall tells the story of the marathoner with a heart of gold, the unlikely ultra-runner, and the hidden tribe in Mexico that runs to live. (Filmed at TEDxPennQuarter.)
