Organized by a NH-based adventure sport racing company, this 12-hour quadrathalon Cannonball Run across 40-50 miles of rugged Southern New Hampshire wilderness pits 3-person teams against one another in four disciplines: Mountain biking, trail running/trekking, paddling, and orienteering, as they navigate the three-legged course using only a map, compass, and the primal desire to meet back up with the Fun Run.
