Audi Power Of Four Race Series

Trail running as part of the Audi Power of Four in Aspen, Colorado.

For elite mountain athletes, the Audi Power of Four Race Series is the quintessential test of endurance, skill and mental fortitude. Stretching across winter and summer, and featuring three disciplines — ski mountaineering (or SkiMo for short), mountain biking and trail running — each race has become a marker in the personal lives of the athletes. The routes vary, but the Trail Run and SkiMo threads together a route that goes up and over Snowmass, Buttermilk, Aspen Highlands and, finally, Aspen Mountain. New this year, the Audi Power of Four Mountain Bike will utilize some of the best single track in the valley over a 25 mile loop that will start and finish in Snowmass.

Whether you are game for the whole enchilada, looking to compete in the shortened series, or you want to cheer on the racers, we have the lowdown for you here.
"You have to have the fitness, because there’s a lot of vertical and you’ll be racing a really long time."
Max Taam, four-time Power of Four SkiMo Champion.

"Finishing a Power of Four race is amazing. Each route between Aspen and Snowmass will involve no less than 8,000 vertical feet of ascent over a minimum of thirty miles. Combined with an incredible backdrop of the Elk Mountains in either winter or summer, a single race is a tough but rewarding experience for any athlete." –Jon Jay, Power of Four "Triple Crown" racer

"(Descending on) skis and bikes are significantly better than the knee-jarring run descents I had experienced during the Trail Run a year prior, but even those were enjoyable in their own way, too." –Jon Jay, Power of Four "Triple Crown" racer
