About This Race
Set in Missouri's Mark Twain National Forest, the Berryman Trail Races offer runners a chance to tackle one of the Midwest's most respected trail challenges. This race follows the historic 26.4-mile Berryman Trail loop, a single-track course that forms part of the extensive Ozark Trail system. With over two decades of history, the event has earned a reputation for providing both marathon and ultra distance runners with a thorough test of technical trail running skills. The course presents continuous rolling hills through dense forest, accumulating 2,500 feet of elevation gain per loop. Runners encounter abundant rocks and roots throughout, along with multiple stream crossings that can vary dramatically based on recent weather. The Brazil Creek crossing at mile 16 is particularly notable, offering one of the few guaranteed water features where runners should expect wet feet. For 2026, the race adds ITRA point qualification, with marathon finishers earning 1 point and 50-mile completers receiving 3 points. The clockwise loop format means 50-mile runners complete the challenging circuit twice, making this an ideal stepping stone for runners progressing from marathon to ultra distances in a supportive, well-established event environment.
The 26.4-mile Berryman Trail loop winds entirely through forested single-track in the Mark Twain National Forest. Runners face continuous rolling terrain with rocky, root-laden sections and multiple stream crossings. The most significant water feature occurs at Brazil Creek around mile 16, where runners should expect to get their feet wet. The western portion of the loop shares 12 miles with the main Ozark Trail corridor.
Marathon runners complete one clockwise loop, while 50-mile participants tackle the circuit twice. The course maintains its technical character throughout, with stream beds that may contain water depending on recent rainfall conditions. Trail maintenance is provided by the Ozark Trail Association and local running groups, ensuring consistent trail conditions year after year.
