The Ninety-Pound Rucksack Challenge is an annual ski mountaineering event that honors the legacy of the 10th Mountain Division, their historic World War II ascent of Italy’s Riva Ridge and their post-war contributions to American skiing.

The event entails ascending a ski slope or backcountry route on February 18th at 7 p.m. local time—the anniversary of the Riva Ridge ascent.

Rucksacks (or backpacks) are encouraged but not required. This is not a timed event - go at your own pace under the stars!

Stay tuned for more details regarding the uphill route!
