🏃‍♂️ Race Overview

Join us on Sunday, June 22nd, 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.
