Course and support The races use a runnable 2-mile loop on double-track dirt road with about 170 feet of elevation gain per loop and roughly 8,500 feet of total gain over 100 miles. An aid station at the softball field provides hot and cold real foods and typical aid station items. The site offers non-porta-potty bathrooms. Overnight campers can use the softball field and experience the night sky during the 24 hour event.
Rules and cutoffs A 2026 rule clarifies that results in the fixed-time events are limited to the mileage completed in the registered race; runners in 24 hour, 12 hour, and 6 hour categories receive official mileage only for that race. The 100 mile race has a 32 hour cutoff for finishers. No mid-race changes between race categories are allowed after registration closes.
Logistics and awards RV parking is allowed at no extra cost but limited to 20 spots. Tent and car camping are available on site; half marathon entrants are not offered overnight camping to conserve space. Each participant receives a race shirt and all finishers receive a medal. Top finishers receive handcrafted awards and 100 mile finishers receive custom buckles. Red Road Racing is registered as a nonprofit organization and funds not used to run the event go to the tribe's youth and family programming.
