Carved by God, Cursed by the Devil

The event is The Marathon of the Sands, one of the world's most brutal adventure races. A 153-mile run through Morocco's Sahara Desert, it is one of the toughest races on the planet. It winds through sand dunes, rock gardens, salt flats, and mountains - all in 120-degree heat. Ted Archer, a top American finisher, tells of the struggles and the people who persevere to conquer this grueling event.
