Marathon and 12-mile trail races traversing difficult, sometimes technical but stunningly beautiful trails, featuring panoramic views of fall foliage displayed on the surrounding mountains. Climbing and descending for about 5,500 feet of elevation gain, runners will enjoy single track, rugged mountain bike, and smooth horse trails while running over and around Fort Mountain, passing the mysterious rock wall built at the top of the mountain over 1,000 years ago.
