Aid stations are located around the loops and provide water, Tailwind endurance fuel, soda, sweet and salty snacks, fruit and basic supplies. Restrooms at aid stations are portable toilets.

Crew and drop bag access are allowed only at the Start/Finish area. Pacers are permitted for the longest events with event check in and pacing rules; pacers are not permitted for shorter distances.
