What is the Ninety Pound Rucksack Challenge?
The Ninety-Pound Rucksack Challenge is an annual ski mountaineering event that honors the legacy of the 10th Mountain Division and their heroic ascent of Riva Ridge during World War II. Participants ascend a local ski hill, mountain, or backcountry route carrying a weighted pack, symbolizing the determination and endurance of the 10th Mountain Division soldiers.
This year marks the 80th anniversary of the Riva Ridge climb. Join us in commemorating their legacy and celebrating the roots of American skiing!
The history behind the challenge
The 10th Mountain Division was a unique unit of mountaineers trained to operate in extreme conditions during World War II. On February 18, 1945, they made history with their daring night-time ascent of Riva Ridge, a steep, heavily fortified peak in Italy that was crucial to breaking Hitler’s Gothic Line.
Believed to be unclimbable, Riva Ridge was minimally guarded. Under the cover of darkness, 1,000 soldiers ascended up to 2,500 feet of icy terrain, carrying 50-pound packs. Their success, achieved without casualties, broke the German defenses, allowing Allied forces to advance and hastening the end of the war in Italy.
After the war, 10th Mountain Division veterans helped shape the American ski industry, founding resorts like Aspen and Vail and inspiring generations of skiers and mountaineers.
