Routes are color coded and marked with ribbon roughly every 200 yards; polka-dot flagging marks turns and blue ribbons indicate wrong-way junctions.

Aid stations are fully stocked every 5–6 miles with fruit, salty snacks, candy, water, and Skratch electrolyte drink; runners are advised to carry at least 20 oz. of water between stations. The event is cupless; participants should bring their own fluid container. Headphones are allowed only on dirt road sections. No dogs are allowed on course.
