Event & Course Info

From the bustling Snowmass Village to Aspen’s serene heart, participants at Golden Leaf Half Marathon get to relish the mountain trails and roads at their fall peak. Starting at about 8,650 ft elevation in Snowmass Village, the route climbs briefly before diving into the Government Trail – a picturesque single track that winds through the aspen forests and meadows between Snowmass and Buttermilk. Navigating dirt roads, rocky terrains, and a series of ascents and descents, the course culminates at Koch Park in Aspen. The diverse trail features, from embedded rocks and roots to potential wildlife encounters, reinforce the essence of a backcountry race.

There is a seven-wave start kicking off at 8:00 am, and the 2023 event introduces two hydration stations, the first at mile 4 and the second after mile 8. However, it’s advisable to come well-hydrated and consider bringing extra hydration supplies. Given the race’s competitive nature, there are cut-off times: 1 hr 10min at the 4-mile mark and 3 hrs 10min just after mile 11.A delicious lunch from Slow Groovin BBQ awaits participants at the finish line, a delightful reward after a grueling run. The post-race festivities include a raffle and awards ceremony. Cash prizes await the top three male and female finishers, and gender and age-group-specific awards are also up for grabs.
