The 2017-18 Common Read selection is Chris McDougall's Born to Run, a text that examines runners who push their bodies to the limit. This nonfiction work examines the lives of the Tarahumara Indians of Mexico, who have honed the ability to run hundreds of miles without rest or injury in sandals. In discovering their secrets, the author takes readers from science labs at Harvard to ultra-road races across America where runners push. A climactic race in Mexico pits some of America's best-known ultra-runners against the Tarahumara tribe, and the winner will surprise.
