Race Info
The Birkie Trail Run Nordic Trek covers 8.5 miles of double-track and logging roads on the American Birkebeiner trail system near Cable, Wisconsin, starting and finishing at the American Birkebeiner Trailhead. Unlike the marathon, half marathon, and 5K, the Trek route has no singletrack and skips the climb to the Mt. Telemark summit, making it the mellowest of the run distances.
