Berryman 50 Mile and Marathon Trail Races

Berryman 50 Mile and Marathon Trail Races

The Berryman Trail Races are set for May 16, 2026, at Berryman Campground in the Mark Twain National Forest between Steelville and Potosi, Missouri. The event is organized by the Saint Louis Ultrarunners Group and marks the 26th annual running of these trail races.

The course consists of an approximately 26.4 mile single track loop. The Marathon requires one loop and the 50 Mile requires two loops. The loop is fully forested and continuously hilly, with about 2,500 feet of elevation gain and loss per loop. Trails include rocks, roots, multiple small stream crossings, and two locations where feet may get wet near Brazil Creek. The route is run clockwise and shares sections with the Ozark Trail.

Distances:

• Marathon one 26.4 mile loop
• 50 Mile two loops of the 26.4 mile course

Aid stations appear roughly every 5 to 6 miles and offer Hylē sports drink, water, soda, and typical ultra snacks. The races are cupless; runners must carry their own bottle or hydration pack. Pacers are allowed only at specified campground locations on the second loop of the 50 Mile race, with limited exceptions requiring prior permission.

Registration policies note no refunds, rollover credit rules for withdrawals before specified dates, and a deadline for transfers and changes. Day use fees and limited primitive camping apply at Berryman Campground. Finisher medals are awarded for each completed loop and age group and overall awards are given.
