The Berryman Trail is an approximately 26-mile single-track loop through the Mark Twain National Forest. Run two loops for the 50-Mile race, one loop for the Marathon. The total elevation gain/loss is 2500 ft/2500 ft per loop.

Plenty of rocks and roots, and at least two opportunities to get your feet wet. Course crosses many other stream beds that may or may not have water in them depending on recent rainfall.
