Audi Snowmass 50 (formerly Power of Four MTB)

August 3, 2023 - August 4, 2023


The Audi Snowmass 50 replaces the event previously known as the Power of Four MTB.  The ride/race showcases the best singletrack in the Aspen/Snowmass region with a 25-mile loop ascending 5000’ feet.   Solo competitors can choose 1 or 2 laps, or you can split duties with a partner in the 50 Team event. The mountain bike race, organized by the Power of Four organizers, is a part of a series under the same name, which includes a ski-mountaineering race, also called the Power of Four, as well as a Trail Running Race race in the summer under the same name.

The Power of Four started as a race going up and down the four local ski mountains, Aspen Mountain, Aspen Highlands, Buttermilk, and Snowmass, representing an extremely difficult challenge.  Organizers devised a new route to provide an even more accessible to riders with a broader range of skill and fitness levels.  Don’t be fooled; this is still a challenging and difficult event that attracts many of the best athletes in the Roaring Fork Valley.  The route starts on Fanny Hill, just above Snowmass Village, and circumnavigates the Snowmass Valley.  The route is almost entirely single-track and hits some of the famous trails of the region, including Rim, Tom Blake, Government, and more.  If you aren’t within easy reach of Aspen/Snowmass or familiar with the area, this is an ideal event to plan a longer stay or vacation around.  Although Mountain Biking is world-class, the road and gravel riding is just as good, not to mention every other mountain sport you can imagine.

  • This is a difficult, but exceptional event. I’m a fit 50+ road rider talked into doing this event by my son. We have family in the area, so it was a great chance to mix the event with a family visit. For context, I reside at sea level and had just 4 days to acclimate to the 8k+ elevation of the Aspen/Snowmass region. In hindsight that probably wasn’t very smart. I could have used a least a few more days. What’s more, although I’ve done a fair amount of mountain biking, I have medium technical skills at best. I rode the event with a partner and took the first 25 mile leg of the 50 mile team event. You have a choice of participating in the 25 or 50 mile solo event, or you the 50 mile team event. 25 miles, with 5k of elevation gain, was all I could handle. The lap took me 4:30 which was among the slowest times. The fastest laps from the strong local field came in around 2:30. Although I had a lot of excuses leading to a tough day in the saddle, the course is absolutely sublime with some of the best single track you can find anywhere. The route hits many of the best trails in/around Snowmass including Government, Rim, and Tom Blake trails. Think dense Aspen tree’s and beautiful mountain vista’s. The full route circumnavigates Snowmass Village. This is not a huge event in terms of participants (about 180 in 2021), however testament to the quality of the event, all the local hotshots come out to ride/race. Even Lance Armstrong, who lives part time in Aspen, participated in the 2021 event in support of his significant other.
