About This Race

The shortest offering provides an introduction to the Green Monster's notorious terrain, making the technical mountain environment accessible to newer trail runners or those seeking a focused workout. Despite the reduced distance, the course maintains the technical characteristics that define this event, offering rocky descents and rooty climbs in a more manageable package. This distance works well for runners building toward longer mountain challenges or those who prefer shorter, intense efforts.

The course winds through the mountainous terrain of Tioga State Forest, featuring rolling singletrack trails punctuated by demanding climbs and technical descents. Runners navigate multiple stream crossings throughout the route, adding both challenge and scenic variety. The terrain showcases the natural beauty of the area near Pennsylvania's Grand Canyon while testing runners with elevation changes and technical sections that require careful footing.
