About This Race
The Berryman Trail Races offers runners a chance to test themselves on Missouri's storied Berryman Trail, a 26.4-mile single-track loop threading through the Mark Twain National Forest. Organized by the Saint Louis Ultrarunners Group for over two decades, this race embodies the unpretentious spirit of Midwest trail running with its focus on forest miles over flashy amenities. The course follows the historic Berryman Trail clockwise through continuous rolling hills, accumulating 2,500 feet of elevation gain per loop. Runners tackle one loop for the marathon distance or two for the 50-mile challenge. The trail demands attention with its technical footing of roots and rocks, plus stream crossings that may soak your feet depending on recent rainfall. Eight aid stations provide traditional ultra fare and hydration, though the race has gone cupless, requiring runners to carry their own bottles or hydration packs. What distinguishes Berryman from more commercialized events is its straightforward approach and reasonable entry requirements. The race attracts a mix of first-time ultra runners drawn to the forgiving time limits (12 hours for marathon, 14 hours for 50-mile) and experienced runners who appreciate the technical challenge without extreme elevation. The forest setting provides consistent shade and scenery that changes subtly with the seasons, making for a contemplative running experience through Missouri's Ozark terrain.
The Berryman Trail forms a complete 26.4-mile loop through the Mark Twain National Forest, running entirely on forested single-track with continuous rolling terrain. The trail shares 12 miles with the main Ozark Trail corridor, connecting runners to a larger trail system that spans across Missouri. Key features include the Brazil Creek crossing around mile 16, where runners can expect to get their feet wet, plus numerous smaller stream beds that may hold water depending on recent precipitation.
The course maintains a technical character throughout with roots, rocks, and typical Ozark terrain challenges. While the elevation profile shows moderate climbs rather than dramatic peaks, the continuous undulating nature means runners rarely find flat sections for recovery. The clockwise direction and forest canopy provide natural navigation cues, though the single-track nature requires attention to footing and trail markers throughout the distance.
