About This Race
The 50-mile distance at Berryman Trail Races demands runners complete multiple loops of the challenging single-track terrain, requiring careful pacing and nutrition management as they encounter the same technical climbs and descents repeatedly throughout the day. This distance serves as an excellent introduction to ultramarathon running for those stepping up from marathon distance, offering the mental challenge of loop racing where aid station familiarity becomes crucial for success. Runners will experience the full spectrum of trail conditions as daylight transitions and their legs accumulate significant fatigue from the extended time on Berryman's rocky, rooted terrain.
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.
