Description from the race website butte100.com/

Welcome to the most difficult mountain bike race in the country: The Butte 100. The Butte 100 race weekend consists of three individual races, a 100 mile, 50 mile and the Sorini 25, 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 races continue to provide the best mountain bike racing experience possible. Thanks for visiting.

Butte 50 Course:
The 50 mile version of the Butte 100 is a crowd favorite with epic amounts of singletrack on the Continental Divide Trail, sweeping views of the Highland mountains, and athletic tests such as the notorious Basin Creek climb. Racers will encounter dense wooded areas with buff packed dirt progressing to loose decomposed granite surfaces. The 50 mile course is sometimes referred to as the "South Loop" because the 100-milers begin their race on the heading to the north portion of the course, before chasing down the 50-milers on the South Loop.
