All runners must be in the starting corral before the top of the hour and must start each loop at the sounding of the bell. Crew access is allowed at the start/finish area and tents or canopies are permitted near the start line. Once on the course, runners may not receive aid from crew or non-competitors; restroom use is the only allowed exception for leaving the course during a loop. No pacers or artificial aids, including trekking poles, are permitted. Race workers and volunteers will provide aid at the start/finish. Organizers give 3-minute, 2-minute, and 1-minute warnings before each loop start.
Course and awards
The loop runs through Camp Jordan Park and includes exterior track, gravel, and grass surfaces. The course is described as flat, runnable, and non-technical.
