Elkhorn Endurance Runs
Elkhorn Endurance Runs is a set of trail races held annually in the Elkhorn Mountains near Helena, Montana. Established in 1989, it is described as Montana's oldest trail ultra and runs entirely on non‑paved trails, primitive roads, and single track through remote backcountry terrain.
Distances offered include:
- 50 Mile
- 50 KM
- 13.1 Mile
Courses feature mountain scenery, long climbs, technical descents, primitive roads, and cold creeks. Participants may encounter hikers, horseback riders, bike riders, and wildlife such as deer, elk, moose, and bear. Some primitive road sections on the 50 mile and 50 km routes can be accessed by ATV or 4WD but access is difficult. Trails are designated for non‑motorized use.
The event is produced by the nonprofit Helena Ultra Runners League (HURL) and is staffed entirely by volunteers. Entry is limited to 250 total entrants across the three races on a first come, first served basis; registration closes the Sunday before the race. Entry fees include well stocked aid stations, race swag, post race food and drinks, raffles and awards; ultra finishers receive a locally produced hand drawn Elkhorn Mountain art print.
Packet pickup is available the day before at the Montana City Volunteer Fire Department with additional pickup on race morning. Drop bags are permitted only at the Town of Elkhorn for 50 mile runners and must be delivered at the pre race meeting. There are cutoff times at aid stations and a finish line cutoff; runners who arrive after cutoffs are not official finishers. Visit the organization's website for the most recent information.
