What is the Ninety-Pound Rucksack Challenge?

Hosted in partnership with the National Ski Patrol, 10th Mountain Division Foundation, 10th Mountain Alpine Club, 10th Mountain Division Descendants and Uphill Athlete, 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.

Individuals, organizations and ski areas are invited to participate in the Challenge—or to create their own. The Challenge is designed for maximum flexibility, offering a plug-and-play event that participating ski areas can adapt to their own rules and regulations.

Courses are determined by participating ski areas or by individuals undertaking a Challenge of their own design. Participants can carry their regular kit, a percentage of their body weight—or no weight at all.

February 18, 2025, will mark the 80th anniversary of the Riva Ridge climb. Join us in commemorating the 10th’s legacy on this historic day as we celebrate the roots of American skiing.

      Hosting the Ninety-Pound Rucksack Challenge is a unique opportunity to honor American ski history, engage your community, and inspire adventurers of all skill levels.

      What You’ll Need to Do:

      1. Choose a Location: Select a safe route where you can climb 1,500–2,500 feet of vertical gain. If you’re a ski resort, this could be a ski slope or designated trail. Backcountry hosts should ensure conditions are safe and accessible.

      3. Manage Registration: Collect waivers and sign-ups with ease using our ready-to-go forms and instructions.

      How do i participate?

      Participating in the Ninety-Pound Rucksack Challenge is an incredible way to honor history while testing your limits. Here’s how to join:

      Step 1: Find Your Route

      • At a Participating Ski Resort: Check out participating ski resorts on the map, where everything is set up for you. They’ll provide a safe route and guidance for the climb.
      • On your own at your home resort/backcountry: Choose your own tribute! Look for a route with 1,500–2,500 feet of vertical gain and assess safety conditions carefully. Ensure it’s suitable for your skill level and equipment. (Pro Tip: Always check local avalanche forecasts if in the backcountry.)

       

       Step 2: Register for the Challenge

      Step 3: Train for the Climb

      Step 4: Choose Your Pack Weight

      • How much weight you carry is entirely up to you. The average GI in 1945 weighed 155 pounds; a 50-pound pack would have represented ca. 30% of their body weight. (Pro Tip: If carrying excess weight, use water so you can safely pour it out before your descent.)

      The Ninety-Pound Rucksack Challenge is for everyone—whether you’re a seasoned athlete or a first-time adventurer. Take the climb at your own pace and enjoy being part of a nationwide tribute to the 10th and the roots of American skiing.
