Despite a few days of above-average temperatures, Vermont’s snow-sports season isn’t over yet. The annual FAT Ski-A-Thon offers not just another day on the slopes, but an opportunity to support High Fives Foundation, a nonprofit that provides resources for mountain action sports athletes with life-altering injuries. Now in its sixth year, this fun-filled fixture invites skiers and snowboarders to complete laps on Sugarbush Resort’s Valley House Quad and contribute what they can to the cause. Participants and supporters alike can get a head start on the fundraising festivities at Saturday’s kickoff party at Waitsfield’s Localfolk Smokehouse, where friends can fuel up on hearty eats and preregister for Sunday’s happenings.
