Ninety-Pound Rucksack Challenge
February 18 @ 6:30 pm - 9:00 pm
Update 8am 2/18/2026:
Due to the storm, we are not opening our lifts this morning. However, we are keeping an eye on the forecasts and may reopen later today if conditions allow. For the Rucksack Challenge, we will make an official call here by 1pm today.
The Ninety-Pound Rucksack Challenge is a ski mountaineering event honoring the legacy of the 10th Mountain Division. Each year, participants at dozens of ski areas across the country ascend their local mountain on February 18 at 7:00 PM to commemorate the anniversary of the historic Riva Ridge ascent.
For the first year at Spirit Mountain, participants will meet at the Grand Avenue Chalet at 6:30 PM with a 7:00 PM ascent. We will skin or hike up Double Jaw and ski down Four Pipe. How much weight you carry is up to you. Some people will be carrying the ninety-pound rucksack but others will be carrying 30% of their body weight. Carry what feels right to you and climb at your own pace. Headlamps are encouraged. After the challenge, head to Riverside Bar & Grill, which will be open for post-event food and drinks until 9pm.
Season passholders and alpine ticket holders can participate for free. You can also purchase a one-time event ticket for $10 (no lift access included), available for pickup at the Grand Ave Chalet starting at 6:00 PM.
