This is a 12-hour endurance competition that is held at the McDowell Mountain Regional Park. It’s one of our most popular events, starting right before sunrise and finishing just after sunset! Take in some awesome views of the Sonoran Desert on this varietal trail while winding through technical turns and dipping into mini canyons. This course is an intermediate 16.5 mi. loop that has a 917 ft. elevation gain and is 60% singletrack. Bring your whole gang to ride, take part in the instructive demos set up by local bike shops, and kick back with a slice from Dough Broughs Wood Fired Pizza. We expect this race to sell out, so register now to ensure your spot and get your free pint glass and t-shirt!
