Welcome to the Butte 100

Saturday, July 25, 2015

Race Director Gina EvansWelcome to the most difficult mountain bike race in the country: The Butte 100. The Butte 100 consists of two individual races, a 50- and 100-mile version, taking place atop the Continental Divide just outside of Butte, Montana.  The race has grown from a small group of dedicated locals on a gravel road, to world-class athletes competing on world-class trails. With outstanding partnerships with the USFS, BLM, community of Butte, our generous sponsors, and the “neon army” of volunteers, the Butte 100 continues to to provide the best racing experience possible. Thanks for visiting.
