Devils Backbone

The Devil’s Backbone returns to Bozeman, Montana on July 11th, offering a challenging mountain running experience along the Gallatin Crest for seasoned backcountry athletes. This year's event features two unforgettable routes: a stunning point-to-point course starting at Portal Creek Trailhead and climbing over Hyalite Peak before finishing at Grotto Falls Trailhead; and an out-and-back route beginning and ending at Grotto Falls, with participants summiting the peak twice in both directions. Both options traverse rugged terrain through the Hyalite–Porcupine–Buffalo Horn Wilderness, rewarding those who come prepared for a remote adventure.
The morning sun casts long shadows over Bozeman as runners gather to take on the 25-Miler starting at dawn from Portal Creek Trailhead. The air is crisp and clear with hints of pine needles carried by the breeze, while night-time participants in the 50-Miler navigate under starlight before sunrise. Each runner carries their own supplies for self-sufficiency, moving through a landscape that demands respect and careful preparation. As dawn breaks over Hyalite Peak, runners are met with panoramic views that remind them why they choose to test themselves against nature’s raw beauty.
This event has become an annual pilgrimage for mountain enthusiasts since its inception in 2014, drawing hundreds of participants each year who contribute donations to support local non-profits dedicated to trail maintenance and public land conservation. The Devil's Backbone not only challenges physical limits but also fosters a sense of community among those who share a love for the outdoors and an appreciation for Montana’s rugged wilderness.
The course itself follows the Gallatin Crest, weaving through technical terrain with significant elevation gain over 25 or 50 miles depending on your choice. The route is largely unpaved, featuring rocky paths and steep inclines that demand careful footwork and endurance. Runners will traverse alpine ridgelines offering sweeping views of Bozeman’s iconic peaks. Aid stations are strategically placed but minimalistic in nature; participants should plan to carry essential supplies such as food, hydration, navigation tools, and emergency gear throughout the race.
Starting at midnight for the 50-Miler, runners face a unique challenge with limited visibility during initial hours. They must navigate through changing conditions from dark nights into early morning light until eventually reaching daylight in full force by late afternoon or evening. The elevation profile sees participants climbing to Hyalite Peak multiple times before descending back down to Grotto Falls Trailhead for the finish line celebration.
In July, Bozeman enjoys an average temperature of 19.6°C with minimal rainfall and consistent sunshine. Runners can expect a range from chilly early morning temperatures around 12°C to warm afternoons reaching up to 27.3°C by late afternoon. The trail conditions are firm yet slightly soft underfoot, providing traction but also requiring caution on loose rocks or slippery surfaces.

Devil's Backbone offers two challenging routes: the 50 Miler (80.5K) and the 25-Miler. Participants must carry essential supplies for self-sufficiency throughout both distances.
