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 each one threads together a route that goes up and over Snowmass, Buttermilk, Aspen Highlands and, finally, Aspen Mountain.

The Power of Four Triple Crown recognizes athletes that have competed in the full distance of all three disciplines (SkiMo, MTB & Run) within the same calendar year. The top 3 combined times of each gender will take home a portion of the $6000 prize purse.
