Mt Sopris Run-off

Mt. Sopris Run-off - Carbondale, Colorado

The Mt. Sopris Run-off is a point to point trail race in the Roaring Fork Valley. The event offers two distances that follow the iconic Up & Over single track route from Flying Dog Ranch to Rock Bottom Ranch in Basalt. The courses use a mix of pavement, dirt road and single track and include sustained climbs, northward traverses, and technical switchback descents.

• 10 Mile: point to point on Up & Over single track from Flying Dog Ranch to Rock Bottom Ranch.
• 25k: point to point on Up & Over single track from Flying Dog Ranch to Rock Bottom Ranch.

Course details include an initial 1.75 mile section on Prince Creek Road, a short single track entry onto Prince Creek Trail and Christmas Tree where runners reach about 2.6 miles and gain approximately 725 feet. Both routes use North Porcupine, Outie and Buckhorn trails; the 25k continues onto Buckhorn Traverse and Glassier before joining the Rio Grande Trail into the finish. Aid stations provide water, electrolyte mix and carbohydrate options; the 10 mile course has two aid stations and the 25k has three. There is a cutoff at the second or third aid station for the 25k with runners redirected to the shorter course if they miss it.

Race weekend also includes a Trail Running Film Festival the day before, shuttle service to the start from Carbondale with no start line parking, a post race gathering at Rock Bottom Ranch with locally sourced grass fed burgers and a vegetarian option, non alcoholic beer for finishers and volunteers, and transportation of drop bags with no responsibility for valuables. Portions of the operation occur on public lands under permit from the U.S. Bureau of Land Management. No dogs are allowed at Rock Bottom Ranch.
