Course, logistics and rules

The course is an approximately 26.4-mile single-track loop. The Marathon is one loop and the 50 Mile is two loops. Each loop is forested and continuously hilly, with about 2500 ft of elevation gain and 2500 ft of loss per loop. The trail has rocks, roots, and multiple stream crossings, including Brazil Creek near mile 16. The race is run clockwise. Aid stations are spaced roughly every 5 to 6 miles and provide sports drink, water, soda, and snacks. The event is cupless; runners must carry their own bottle or hydration pack.

Pacers are allowed only at Berryman or Brazil Creek campgrounds on the second loop of the 50 Mile. There are finisher medals for one-loop and two-loop completions and age-category awards plus top overall awards. Parking and a day use fee apply at the campground. Primitive camping is available at Berryman and limited free primitive camping at Brazil Creek. No refunds; rollover credits and bib-transfer rules apply, with a final change deadline of May 11. A post-race barbecue will be provided; runners are asked to bring non-disposable plates and utensils. Visit the organization's website for the most recent information.
