Revisiting Endurance Athletes

Jennifer Pharr DavisThis week we’re revisiting a great show about some incredible athletes. Jennifer Pharr Davis hiked the Appalachian Trail in 46 days, averaging 47 miles a day. David Johnston finished the 350-mile Iditarod Invitational in four days, running on snow. They’ll both join us as we try to understand what makes ultra-endurance athletes tick. Their accomplishments are almost super human. How do they get that way, and what makes them go?
