Join us on Sunday, June 21st, for the Sunset Trail Running Festival in Gold Hill, CO! Hosted by The Boulder Watershed Collective and in collaboration with T.E.A.M Boulder, all money raised from the event will be donated to the town of Gold Hill, and will fund wildfire preparation and response initiatives such as forest restoration, home hardening, emergency planning, land stewardship, and community resiliency.

This event provides an opportunity for the Front Range trail community, to show its support for small mountain town communities that live with a high risk of disruption and destruction from wildfire, while providing visitors with access to their unique character, beauty, and the surrounding landscapes.

RACE DETAILS Runners can choose between a 28K (17.4M), 12K (7.7M), 5K, or Kids 1K trail race. All distances start and finish on the main street of Gold Hill at the Gold Hill Inn, and the longer distances are run, in part, on the National Forest System roads. Runners will enjoy varied terrain of dirt roads and trails through ponderosa pine and aspen forests while taking in amazing views on these challenging courses.

The 28K course heads south to Salina, and then west along Fourmile Canyon Dr to the historic town of Sunset. From there, runners will head north up the Switzerland Trail and back to Gold Hill. The 12K course heads west along Gold Hill Rd to the famous Mount Alto Picnic area and back into town.
