The Sunset Trail Running Festival is a promotion of health, fun and fitness while supporting a tax-exempt organization/partner, the Fourmile Watershed Coalition and Fire District, which is working to increase the health and resiliency of our forests by restoring natural conditions through strategic thinning, prescribed burning, reforestation in burn areas and education.
