Grind your poison, shred your fun!

This epic mountain bike endurance event offers four distances—Filthy 50, Dirty 30, Unclean 15, and Slimy 7—on a 7.5-mile XC-style loop through the rolling singletrack of Bedford County, Virginia. With sections for all skill levels, racers can expect a festive and family-friendly weekend complete with camping, music, and a lively post-race party. The event is hosted by RVA Racing Events and draws both competitive and novice riders to experience the thrill of both the trail and the vibrant race community.

Four race options: 50, 30, 15, and 7 miles. Each is based on repeated laps of a 7.5-mile singletrack loop featuring rocky, rooty sections, smooth rhythm stretches, and a handful of technical elements. The course combines fast flow, moderate climbs, and manageable technical features, making it accessible for riders of all abilities.
