Born to Run: Mexico's Tarahumara Indians

In 2006, Scott Jurek, one of the world's best ultramarathon runners, travelled to the remote canyons of Northern Mexico to race the best athletes from an ancient Mexican tribe. The Tarahumara have a tradition of running huge distances and they gave Jurek one of his toughest races, inspiring the best-selling book, Born To Run. Scott Jurek talked to Simon Watts in 2014.
