The start and finish are located at the Competitive Track Area near the park entrance, just beyond the ranger station. Course markings include orange plastic ribbons with black polka dots, reflective medallions, laminated signs at junctions, and blue and white checkerboard flagging to indicate wrong-way trails. Runners are encouraged to review course maps and use GPX files or printed maps.
Aid support includes one full remote aid station (Gate Aid) and a water-only aid station passed each loop. Aid stations are stocked with water, ice, electrolyte drink options, salty and sweet snacks, fruit, pb&j, bean rollups, and hot food such as quesadillas and grilled cheese. Crews are allowed only at the start/finish area. Pacers are not allowed for any distance. A designated area for drop bags is available at the start/finish.

Pets are not allowed on-course during the night runs and must be leashed and supervised if present at the event. The event is cupless; runners should bring their own cup or purchase a reusable option. Visit the organization's website for the most recent information.
