About the race
The Copper Kings 100 is a one-loop 100 mile trail race in Butte, Montana, scheduled for June 25-26, 2027. The course starts and finishes at the Belmont Mine and includes about 63 miles on the Continental Divide Trail. The event takes place in the Beaverhead-Deerlodge National Forest and within Butte-Silver Bow and Jefferson counties, and it is fully permitted by relevant agencies.
Terrain is high-elevation mountain trail. The course begins near 5,650 ft and rises to about 8,400 ft, with a total of 13,960 feet of vertical gain and loss. Much of the route lies above 6,500 ft. Elevation gain is concentrated between the first and last aid stations, and some aid stations are widely spaced, with the longest segment over 17 miles. The event uses a 40-hour overall cutoff and offers a nonbinary division.
Registration opens in December, timed to follow the Western States lottery draw. The 2027 edition is an official qualifier for the 2028 Western States Endurance Run. Proceeds benefit the Continental Divide Trail Coalition, Our Lady of the Rockies, Mile High Nordic Ski Education Foundation, and the Montana Endurance Trail Foundation. The event is produced by Onward Endurance LLC in partnership with the Montana Endurance Trail Foundation.
The withdrawal policy converts part of an entry into a race credit when cancellation is at least 60 days before race day; fewer than 60 days yields no credit. If organizers cancel the event, no refunds are provided. Visit the organization's website for the most recent information.
