American Birkebeiner Ski Foundation

Located in Northern Wisconsin, the American Birkebeiner is the largest cross-country ski race in North America, and one of the longest. It debuted in 1973 and was a founding member of the Worldloppet federation of cross-country ski marathons.

The non-profit 501(c)(3) American Birkebeiner Ski Foundation maintains 100% of the trail system. Donations to help cover the annual maintenance costs are welcome. You can help with a personal donation which may be tax deductible (consult your tax professional) and by joining the Foundation. We think the American Birkebeiner Trail is a pretty fantastic recreational resource. If you think it is as spectacular as we do, we’d love your support in making sure it stays amazing for generations to come.
