Event Information

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
12-Hour (Day)
12-Hour (Night)
24-Hour

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

Course & Rules

The loop features optional creek access for cooling. The event operates as a "no aid course," meaning no food, drink, ice, gear, pacing, or assistance of any kind is allowed on the loop itself. Aid may only be received in a runner's personal aid area. Receiving aid outside this area results in immediate disqualification.

Additional Details

The event encourages participants to bring a dish to share, with awards for the best dishes. Smoked BBQ, a vegetarian meal, water, and sports drink will be provided. Well-behaved dogs and camping are permitted on the property, subject to specific rules. Visit the organization's website for the most recent information.
