About This Event

The Icebug Birkie Trail Run transforms the legendary American Birkebeiner ski course into a challenging trail running experience through northwest Wisconsin’s glacial terrain. This event stands out for its unique course composition—80% wide ski trails and 20% technical singletrack—creating a distinctive mix that few trail runs can match.

The course’s glacial topography defines the challenge. Expect relentless short, steep climbs up to 50 feet with grades hitting 10-20%, followed by quick descents that test your quads and technique. The wide ski trails, mostly grass-covered with some dirt sections, contrast sharply with the winding singletrack portions featuring tight switchbacks, rocks, and roots.

Race options span from a 5K introduction to the full USATF Mountain Ultra Trail Marathon Championship, which draws top national competitors. The marathon course climbs to Mt. Telemark’s summit, offering panoramic views that veteran participants consistently highlight as a race highlight. Half marathon runners tackle 13.1 miles of the same varied terrain, while the marathon relay allows teams of 3 or 6 to tackle the full distance together.

The event maintains strong community roots through the American Birkebeiner Ski Foundation, connecting trail runners to the historic Birkebeiner legacy. Aid stations are strategically placed throughout longer courses, and the post-race atmosphere includes complimentary Earth Rider beer and celebration at the finish.

Prize money rewards top marathon finishers, while age group awards recognize performances across all distances. The Friday night Trail Running Film Festival adds an inspiring prelude to race weekend, building anticipation for your own Birkie Trail adventure.

The event includes a full festival weekend with additional races, events, and community celebrations.
