Audi Power Of Four Race Series

Audi Power of Four Bike Race at Aspen Snowmass

The Audi Power of Four Series at Aspen Snowmass epitomizes the spirit of endurance, challenging athletes through three distinct events. Each race in the series is a testament to the indomitable mountain spirit and a showcase of peak athletic performance. The Audi Power of Four Ski Mountaineering Race, a winter highlight, features a 24-mile journey ascending 10,000 feet across our four iconic mountains. For those seeking a shorter challenge, the Audi Power of Two offers a condensed yet equally exhilarating experience with breathtaking vistas and demanding climbs.

The Audi Power of Four Trail Run, a summer staple, presents a spectrum of races including the 10K, 25K, and the 50K Ultra. Participants embark on a scenic yet demanding adventure from Aspen Mountain's base to the verdant trails of Snowmass, weaving through the stunning Elk Mountains.

Biking enthusiasts will relish the Snowmass 50 Mountain Bike Race, a rigorous 25-mile loop that ascends 5,000 feet, suitable for both solo riders and teams. This course traverses Snowmass's finest singletrack trails, ranging from high desert sage meadows to dense, loamy forests.

We invite you to join us in the heart of the Rockies for these extraordinary events, where you'll be challenged to push your limits, embrace the essence of mountain adventure, and forge unforgettable memories at Aspen Snowmass.


"You have to have the fitness, because there’s a lot of vertical and you’ll be racing a really long time."
