The course is flat crushed gravel, mostly out-and-back along the trail, with sections of single-track and old rail-bed, passing prairie landscapes and the Marais Des Cygnes River. The event is described as a festival-like ultra party, with well-stocked aid stations every ~4 miles, music, shirts, and unique awards at finish. Pacers allowed for long distances; drop bags; late registration; part of the Kansas Super Slam. Visit the organization's website for the most recent information.
