Berryman 50 Mile and Marathon Trail Races
Potosi, United States • 17 May 2025
The Berryman 50 Mile and Marathon Trail Races take place at Berryman Campground in the Mark Twain National Forest near Potosi, Missouri. The event features two distances: a 50-mile ultra and a marathon, both run on the historic 26.4-mile Berryman Trail loop. The marathon covers one loop, while the 50-mile race requires two loops of this forested, hilly single-track trail with 2,500 feet of elevation gain per loop.
The course includes rocky terrain, roots, and stream crossings. Aid stations are spaced every 5-6 miles, offering hydration and snacks. The race emphasizes environmental care with a cup-free policy, requiring runners to carry their own hydration.
Post-race festivities include a BBQ for participants. Visit the organization's website for the most recent information.
