HURL Elkhorn

The race venue is set within the Elkhorn Mountains, where participants face rugged trails, steep elevation changes, and remote stretches far from civilization. Race morning will see temperatures ranging between 12.1°C at dawn to around 27.5°C by midday, with a consistent humidity of about 49% throughout the day. The terrain is firm but slightly soft underfoot, ideal for trail running shoes or light hiking boots.
Since its inception, HURL Elkhorn has attracted endurance athletes from across Montana and beyond who seek to push their limits in one of the most challenging races in North America. Each year, finishers report a mix of awe-inspiring beauty and technical difficulty that tests both physical prowess and mental resilience. The race raises funds for local conservation efforts aimed at preserving these unique landscapes.
The course winds through single-track trails and primitive jeep roads deep into Montana's backcountry. Runners will encounter significant elevation changes with approximately 13,400 feet of gain on the full 50-mile route and around 7,900 feet for the 50K distance. Aid stations are well stocked but few and far between; the longest gap is seven miles for the longer races and eight miles for the half marathon.
Racers can expect mild winds at an average of 7.8 km/h and a UV index that falls into the moderate range, requiring sunscreen application to avoid sunburns during prolonged exposure in open areas. With only minimal rainfall expected—0.9mm on race day—the trail conditions are likely to remain firm but soft enough for comfortable running.
HURL Elkhorn offers three distances: an 80.5K (50-mile) course, a 50K route, and a half marathon at 21.1K. Registration fees start at $65 for the half marathon and go up to $130 for the full ultramarathon distance.
