The aid station is fully stocked with a rotating variety of food, cooked to order items such as quesadillas and soup, and dinner items that may include pasta, tacos, burgers, donuts, or a spaghetti taco. A separate water only station is planned with a canopy roughly halfway through the loop. Additional on site amenities listed for past events include massage therapists, food trucks, family cheer zones, portable restrooms, and social areas with music and games.

Awards and support details include buckle awards for 100 mile, 150 mile, and 200 mile milestones, a 100 percent rollover policy up to 24 hours before the race, and relay team rules that limit teams to four to ten runners sharing a single team bib.
