Snow Mountain Ranch 33K

2026

The Snow Mountain Ranch 33K covers 20.2 miles of dirt and grass trails through the Colorado Rockies near Granby, with runners tackling two loops that climb to 9,844 feet. The course format features an out-and-back with lollipop sections, gaining roughly 2,400 feet total with the major climbing happening between miles 3-6 on each loop. September conditions at this altitude can bring anything from warm sunshine to sudden weather changes, so preparation matters. The route moves through classic Colorado high country terrain—rolling hills, meadows, and forested sections that showcase fall colors. Seven aid stations provide support throughout the two-loop journey, with drop bags available at the start/finish area between loops. This race suits runners comfortable with sustained climbing at altitude and those who don't mind repeating terrain. The 8-hour time limit allows for a steady pace, but the elevation and loop format create cumulative fatigue that can surprise runners new to high-altitude racing. If you enjoy mountain views and can handle thin air, the course delivers solid trail running without excessive technical challenges.
