Course Description

The course is a roughly 6-mile loop on trails. Surfaces include gravel, grass, roots, and forest duff. The route passes through forested areas, open fields, and meadows. It includes a short section along a paved bike path near Ballaine Lake, where runners can use adjacent gravel or grass. The trails are described as mildly technical, with roots, occasional branches, and potentially soggy spots depending on conditions. There are no road crossings, aside from a few gravel maintenance roads.

The start area is near the ski hut behind the International Arctic Research Center at UAF, at 930 Koyukuk Drive, Fairbanks. A post-race BBQ and awards ceremony are held after the event.
