Course Maps
Adjusted courses for 2025! The 30K and 20K will ski on a 5K loop. The 10K and 5K will ski on a 2.5K loop. There will be some overlap, but we’re working on the timing of the races to avoid congestion on the trail. We want everyone to be able to ski at their own pace- no matter what that is!

Wax Policy
The American Birkebeiner Ski Foundation has joined U.S. Ski and Snowboard in banning the use of fluorinated ski wax in competition beginning the 2020-2021 season. We encourage all competitors to abide by this policy for all events on the Birkie Trail and at the American Birkebeiner Trailhead. All athletes are subject to random ski testing at events and penalties will apply to any US Ski and Snowboard licensed or citizen skier that is found to be non-compliant.
