About This Race
The Cacapon 12 Hour Challenge stands as a testament to grassroots trail running, entering its 14th year with the same passionate commitment that earned it the 2017 RRCA West Virginia Ultra State Championship designation. Set in the scenic woodlands near Berkeley Springs, this time-based event challenges runners to cover as much ground as possible on a demanding 5-mile loop within the 12-hour window. The race organizers, Jason and MJ, have cultivated something special here—a community-driven event where exceptional volunteer support and thoughtful race management create an atmosphere that keeps runners returning year after year. The course itself is unforgiving, rated (4,4) on the Ultrarunning.com scale, with approximately 750 feet of elevation change per loop across moderately to very technical single-track terrain. What sets this challenge apart is its focus on personal achievement within a supportive community. Runners tackle stream crossings, navigate technical terrain, and push their limits while being sustained by comprehensive aid station support and the encouragement of fellow participants. The post-race meal and camaraderie extend the experience well beyond the finish line, making this more than just a race—it's an annual gathering of the trail running tribe.
The 5-mile loop follows scenic single-track trails through moderately to very technical terrain, with approximately 750 feet of elevation change per circuit. Runners encounter stream crossings that vary with recent rainfall, navigate well-marked and maintained trails, and cross lightly-traveled park roads at several points throughout each loop. The course direction has been reversed from earlier years, adding a fresh challenge for returning participants.
The technical nature of the terrain, combined with the repeated loop format, creates a unique mental and physical challenge as conditions change throughout the 12-hour period. The trail's (4,4) rating on the Ultrarunning.com scale reflects significant technical demands that will test even experienced ultra runners.
