Nova's Marathon Challenge

This Nova program uses the story of a group of non-athletes who train for the Boston Marathon as the vehicle to introduce a lot of other great material about nutrition and health, the interaction between genetic and environmental influences on fitness and athletic potential, the possibility of changing health behaviors in mid-life, and (perhaps unintentionally) about the ridiculous difficulty of running a marathon. You may find it motivating even if it doesn't make you want to run a marathon in particular. The show features Professor Miriam Nelson, from the Friedman School of Nutrition Science and Policy at Tufts University, in a starring role as both team scientist and inspiration.
