The course is one roughly 10.5 mile loop run one, two, or three times depending on distance. Surface composition is approximately 75% single track with roots, rocks, and wooden bridges, 20% forest road, and 5% crushed gravel along the dam. Several small hills produce about 500 feet of elevation gain and loss per lap; there are no significant sustained climbs. Trail markings are present and a GPX file of the route is provided by the organizer. Mud or wet sections may occur and are usually avoidable while staying on the trail.

Aid and logistics include a main staffed aid station at the park entrance on Camp Cosoma Road with warm food, drink, toilet facilities, and a small covered area. A second aid station near the Salem Forest parking lot on Indian Bridge Road offers food, drink, and a porta potty; runners may use drop bags there but should plan to recover them after the event. The event shares trails with other users such as mountain bikers, walkers, leashed pets, and horseback riders.

The event is limited to 100 participants. A day use vehicle charge applies at the park entrance with different rates for Maryland and out‑of‑state residents, paid by credit card at the automated gate. Visit the organization's website for the most recent information.
