Telluride Mountain Run 13 Mile

2026

The Telluride Mountain Run 13-mile takes place in late August in the San Juan Mountains above the historic mining town of Telluride, Colorado. This technical mountain race follows old mining roads, singletrack, and alpine tundra as it climbs to 12,900 feet on Gold Hill ridge, delivering substantial elevation gain in thin air that will test most runners. The course starts and finishes at Telluride Town Park, navigating exposed ridgelines and high-altitude terrain where the striking colors of the San Juans provide scenery between the inevitable oxygen debt. Runners move through varied terrain from mining roads to alpine tundra, with four aid stations spaced across the route. An 8-hour time limit reflects the challenging nature of the elevation and technical terrain. This race suits experienced mountain runners comfortable with sustained climbing at altitude and technical footing. If you struggle with thin air above 12,000 feet or prefer less technical terrain, this might not be your race. Runners who enjoy grinding out elevation in spectacular high-country settings will find exactly what they're looking for here.
