      Beginning at Camp Shenandoah, this out-n-back course ascends and descends Little North Mtn before climbing over 2400ft in 4 miles to the summit of Elliot Knob. The course then proceeds north following the ridgeline of Great North Mtn crossing over to and following the Wild Oak National Recreation Trail before continuing north to the summit of Reddish Knob. Runners continue north to Briery Branch Gap before retracing their steps (without summiting Elliott & Reddish) back along the course to Camp Shenandoah.
