Devil's Backbone : Bozeman, MT
The Devil's Backbone is a mountain running event in the Gallatin Crest near Bozeman, Montana. The course runs through the Hyalite–Porcupine–Buffalo Horn Wilderness and follows alpine ridgelines and high-country terrain. The route features significant elevation gain, technical trails, exposed sections, and limited support. Participants are asked to carry food, hydration, navigation tools, and emergency gear due to changing mountain weather and backcountry conditions.
Distances
- 25-Miler: Point-to-point Portal Creek Trailhead to Grotto Falls via Hyalite Peak.
- 50-Miler: Out-and-back starting and finishing at Grotto Falls with Portal Creek turnaround.
