About This Race
The Berryman Trail Races take runners deep into Missouri's Mark Twain National Forest for what has become a cherished fixture on the Midwest ultra calendar. Now in its 26th year, this event showcases the rugged beauty of the Ozark Mountains through a challenging single-track loop that tests both endurance and technical trail skills. The race is organized by the Saint Louis Ultrarunners Group, reflecting the grassroots spirit that makes it a genuine community gathering for trail runners across the region. The course follows the historic 26.4-mile Berryman Trail, which forms part of the larger Ozark Trail system. Runners tackle one loop for the marathon distance or push through twice for the 50-mile challenge. The terrain demands constant attention with its rocky, root-strewn surface and continuous elevation changes that accumulate 2,500 feet of gain and loss per loop. Creek crossings add an element of unpredictability, particularly at Brazil Creek where runners can expect wet feet regardless of recent weather. Practical considerations reflect the race's commitment to environmental stewardship. The event operates as a cupless race, requiring all participants to carry their own hydration systems throughout. With a 14-hour cutoff for the 50-mile distance and comprehensive aid station support every 5-6 miles, the race balances challenge with safety. The early morning start times and forest service day-use fees are additional logistical factors that runners should plan for when considering this authentic trail running experience.
The Berryman Trail presents a classic Ozark Mountain challenge through 26.4 miles of continuous single-track. The entirely forested loop winds through dense woodland with persistent elevation changes, rocky technical sections, and root-covered trails that demand focused footwork. Multiple stream crossings punctuate the course, with Brazil Creek at mile 16 serving as the most significant water obstacle where runners should expect to get their feet wet regardless of conditions.
Running clockwise around the loop, the course shares 12 miles with the main Ozark Trail corridor, connecting this race to Missouri's broader trail running heritage. The terrain maintains its challenging character throughout, with no extended flat sections to provide relief from the technical demands. Each loop accumulates 2,500 feet of elevation gain, creating a cumulative challenge that intensifies significantly for 50-mile participants tackling the route twice.
