Running the Sahara (2007)

Three ultrarunners, Charlie Engle, Ray Zahab and Kevin Lin, set out to cross the Sahara on foot from the Atlantic to the Red Sea, and the film follows the 111 days it took through six countries. This is the expedition film of the list: heat, wrecked feet, a diplomatic snag in Libya, and the strain of running beside the same two people every day for months. Matt Damon narrates. It suits a crowd who prefer an adventure story to a race.
