Aspen Snowmass presents the 9th annual Audi Power of Four Mountain Bike race. This year, the course is a fully new design. Riding as a loop rather than a point to point, riders will start and finish in Snowmass. The 2019 course is going to utilize some of the best single track in the valley over a 25-mile loop that will start and finish in Snowmass Base Village. The full Power of Four division will do 2 laps of the course while the Power of Two division will do 1 lap. Focused on the amazing trails of Snowmass, this course follows the Snowmass Loop. The course is fast, flowy, and technical in spots. It is a world-class race on world-class trails.
