Hell Mary is an endurance run held on a 1-mile flat loop in an open field with minimal shade. The course has minimal technical terrain and an approximate elevation gain of 50–60 feet per mile.
The event offers multiple timed divisions:
- Hell Mary 6 Hours

Placement is determined by the miles completed within a participant's selected division. All runners will be assigned a designated 10x10 personal aid area.

Aid may only be received in a runner's personal aid area. Receiving aid outside this area results in immediate disqualification.
