5K
The 5K at Brundage Mountain Summit Cat Track offers newcomers to mountain running an accessible introduction to high-altitude trail racing without the extended commitment of the 10K distance. Runners tackle the same challenging cat track terrain but with a shorter exposure to the elevation and technical demands, making this distance ideal for those testing their mountain legs or seeking a fast, intense effort at altitude. The abbreviated distance allows runners to push a harder pace while still experiencing the unique demands of summit racing, creating an excellent stepping stone for those considering longer mountain challenges.
10K
The 10K follows the Cat Track, a ski area service road that provides a steady, sustained climb to Brundage Mountain's summit. Runners gain 1,640 feet over 3.1 miles of ascent, reaching the turnaround point at the Bluebird chairlift where an aid station awaits. The route offers 360-degree views from the summit before runners descend the same path back to the base. The 5K course reverses this experience, beginning with a chairlift ride to the summit starting line. From there, runners enjoy a continuous 3.1-mile descent along the same Cat Track, losing 1,640 feet of elevation as they make their way back to the finish line at the resort base.
