All courses run on heavily wooded trails with several hills and technical obstacles such as tree roots, stones, and steep inclines. The listing notes specific water station coverage by distance: two stations on the 5k, two on the 10k, six on the half marathon, and twelve on the full marathon; Gatorade is available at some stations. Portajohns will be available near the start and finish area.
Runners receive a finisher’s medal, a technical (drifit) event shirt, and chip timing. Live results will be posted online and accessible via a QR code at the race; final results with series points are posted the Monday after the race. Points from this event count toward year-long 5k, 10k, endurance, Back of the Pack, and Winter Series standings. A virtual run option is offered for participants who cannot attend in person.
