Blue Sky Trail Marathon

The Blue Sky Trail Marathon, held in Fort Collins, CO, is the region's original trail marathon, featuring both a marathon and a half marathon. The event showcases scenic trails between Horsetooth Mountain Park and Devil's Backbone Open Space, with a challenging course that includes over 3,500 feet of elevation gain and loss. Designed for both experienced trail runners and newcomers, the route consists of 100% dirt paths, primarily on Colorado singletrack.

Participants can enjoy a generous nine-hour cut-off time, and post-race festivities include a barbecue and sponsor giveaways. Visit the organization's website for the most recent information.
