We speak to Sanjay Rawal, director and producer of the documentary 3100: Run and Become, which follows a 3100-mile race, in which participants run 60 or more miles a day for 52 days. And we talk to Dustin Quinn Martin, executive director of Wings of America, a non-profit organization that encourages Native Americans to run, as a way of both connecting to ancestors and the land, and to greater achievement in the world.
