Power of Four Mountain Bike Race

Course Information button   Racer Information button   Results button  

This unique mountain bike race combines the four ski areas of Aspen Snowmass (Snowmass, Buttermilk, Aspen Highlands and Aspen Mountain) into one amazing mountain bike race. The diversity of the terrain and tackling our four distinct mountains has placed this race in a category all its own. 

The field consists of solo racers and relay teams (of two or four) from the avid bike community that exists in Aspen Snowmass, Colorado and beyond. Racers will start at the base of Snowmass and finish at the base of Aspen Mountain in Gondola Plaza.  With 9,000' vertical gain and drop over 36 miles on top-rated single track, demanding double track ascents and coverage on each of our four mountains this race will challenge even the fittest riders. Experience the Audi Power of Four!

The race will award a $2,500 prize purse. The top three men (1st - $750, 2nd - $350, 3rd - $150) and women (1st - $750, 2nd - $350, 3rd - $150) finishers will be paid out of the purse. 

All registered racers will receive a Helly Hansen piece as well as a custom gift.

We are looking for race volunteers. Volunteers will receive a Helly Hansen piece.
