Event Update

The Ski Mountaineering Challenge has been canceled.


Skin to Win

Lung–burning fun for all at the Ski Mountaineering Challenge. Starting from Canyon Lodge, participants will skin their way through 5 ascents on Mammoth Mountain to complete this battle against themselves and the terrain. Ski mountaineering (ski mo), a high-altitude up and down challenge imported from Europe, is rapidly becoming one of the hottest new winter sports in North America. Mammoth's Ski Mountaineering Challenge is completely in-bounds, offering a safer and more convenient route than in the back-country, opening this new opportunity to competitors of all skill levels.
