Snow Mountain Ranch 10K

2026

The Snow Mountain Ranch 10K in Granby, Colorado covers 6.2 miles of dirt trails with 653 feet of climbing. This single-loop course features an out-and-back format with two lollipop sections, hitting two main climbs between miles 1-2 and 3-4 before reaching a maximum elevation of 8,880 feet. Running at altitude in September, you'll move through varied terrain on well-established dirt trails around the YMCA of the Rockies property. The course design keeps things interesting with direction changes and different views as you work through the lollipop sections. Two aid stations provide support along the way, with the main checkpoint at North Pole around mile 2. This works well for runners comfortable with moderate climbing at elevation who want a solid workout without committing to a longer distance. The 5+ hour time limit is generous, but the altitude and rolling terrain will demand respect even over this shorter distance. Those sensitive to elevation or looking for a flat course should consider their comfort level above 9,000 feet.
