Silverton Alpine Marathons

The Silverton Alpine Marathons, held in Silverton, Colorado, offer trail running adventures through the stunning San Juan Mountains. Participants can choose from three distances: an 8-mile out-and-back, a marathon (~26.8 miles), and a challenging 50K (~31.8 miles). The marathon and 50K courses traverse historic mining ghost towns like Howardsville, Eureka, Animas Forks, and Gladstone, with the highest elevation reaching 12,930 feet at California Pass.

The races start and finish at Silverton Memorial Park, featuring significant vertical gains (up to 4,569 feet for the 50K). The event emphasizes a rugged alpine atmosphere, well-stocked aid stations, and a commitment to environmental stewardship with a cupless race policy.
