Blue Sky Trail Marathon

The Blue Sky Trail Marathon and Half Marathon will take place on October 18-19, 2025, in Fort Collins, Colorado. This event features a challenging 26.7-mile marathon and a 13.1-mile half marathon, both set against the stunning backdrop of the Colorado Rockies. The courses traverse a mix of dirt singletrack and rocky trails, with significant elevation gains, making it suitable for both experienced trail runners and newcomers.

Participants can enjoy well-stocked aid stations, a post-race BBQ, and unique finisher awards. Registration opens on December 15, 2024, with a cap of 600 runners for the marathon. Visit the organization's website for the most recent information.
