Ski mountaineering is a timed racing event that follows an established trail through challenging winter alpine terrain while passing through a series of checkpoints. Racers climb and descend under their own power using backcountry skiing equipment and techniques. More generally, ski mountaineering is an activity that variously combines ski touring, Telemark, backcountry skiing, and mountaineering. It is planned by the Union Internationale des Associations d’Alpinisme (UIAA), to make ski mountaineering by itself part of the 2018 Olympic Games.
