Berryman 50 Mile and Marathon Trail Races
Potosi, United States • 16 May 2026
Event Overview
The Berryman Trail Races are held on Saturday, May 16, 2026. The event offers a Marathon and a 50 Miler distance, both run on the historic Berryman Trail. The start and finish location is the Berryman Campground in the Mark Twain National Forest, between Steelville and Potosi, Missouri.
Course Details
The course is a single-track loop that is approximately 26.4 miles long. The marathon is one loop, and the 50-mile race is two loops. The loop is entirely forested and continuously hilly, with a total elevation gain and loss of 2500 feet per loop. The surface has many rocks and roots. The course includes several stream crossings, with at least two that can wet runners' feet near the Brazil Creek aid station. The 2026 edition will award ITRA points: 3 points for the 50-mile finishers and 1 point for the marathon finishers.
Aid and Logistics
The race is cupless; no disposable cups are provided at aid stations. Runners must carry their own bottle or hydration pack. Aid stations, located approximately every 5 to 6 miles, provide Hylē sports drink, water, soda, and typical ultra snacks. Pacers are only allowed for the second loop of the 50-mile race and only at specific aid stations. Parking is limited at the campground. A $5 day-use fee per vehicle is required for the Berryman Day Use area, payable by cash in a self-pay envelope.
