About This Event

Recognized by Trail Runner Magazine as one of “America’s 14 Most Scenic Races,” this intimate half marathon caps at 750 runners and takes place at the peak of Colorado’s fall color season in late September. The course showcases why it’s considered one of the most beautiful trail races in the Rockies.

Starting at 8,650 feet in Snowmass Village, the route climbs briefly before dropping onto the Government Trail, a stunning single track that winds through aspen forests and meadows between Snowmass and Buttermilk. The course combines dirt roads, rocky terrain, and rolling elevation changes as it makes its way to the finish at Koch Park in Aspen. Runners navigate embedded rocks, roots, and occasional wildlife encounters that emphasize the backcountry nature of this race.

The event uses a seven-wave start beginning at 8:00 am to manage the field on the narrow single track sections. Two aid stations provide hydration at mile 4 and after mile 8, though the high altitude and remote sections make carrying additional water advisable. Competitive cutoff times keep the race moving: 1 hour 10 minutes at mile 4 and 3 hours 10 minutes just after mile 11.

Post-race festivities center around Slow Groovin BBQ’s lunch spread at the finish, followed by a raffle and awards ceremony. Cash prizes go to the top three finishers in each gender, with additional age group awards recognizing the depth of competition this scenic course attracts.
