About This Race
The 10K doubles the challenge of the 5K route, requiring runners to complete two full loops of Brundage Mountain's demanding cat track terrain. This distance tests both climbing endurance and descent control as legs fatigue through the second ascent, making it ideal for runners ready to progress beyond a single-loop effort but not yet committed to longer mountain distances. The repeated loop format allows runners to refine their pacing strategy after experiencing the full course profile once, though the second climb presents a notably different challenge with pre-fatigued muscles.
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.
