About this race

The East Fork races return for their third year on challenging trails around William H. Harsha Lake in East Fork State Park. The course includes mountain bike trails, hiking trails, and the Steve Newman Worldwalker Perimeter trail. Expect rolling terrain with many smaller rollers, lake views, single track, and creek crossings. The course runs slightly long, with a 40-hour cutoff to help participants succeed. New start times are implemented to avoid crowding.
