Arizona: 24-Hour Mountain Bike Race

The "Burning Man" of the mountain biking world, this race attracts some of America's most eccentric mix, as competitors pedal a 24-hour loop course through the wild and dangerous cacti forest of the Sonoran Desert. The squad experiences equipment breakdowns, a race-stopping emergency, night time exhaustion and the fight to work their way onto the podium.
