Hell Mary

About the Event

The Hell Mary endurance race returns to Watertown, Tennessee on July 18th, challenging runners with a flat, unforgiving course that tests speed discipline and heat management. Located at 10010 Statesville Road in the heart of town, participants will run through an open field with minimal shade but optional access near a creek for cooling breaks during their selected time division.
On race day morning, temperatures typically hover around 26 degrees Celsius as runners gather on the flat loop course. The setting sun and cooler evening air make way for nighttime divisions starting at 9:00 PM under limited visibility conditions. Runners must manage hydration and pacing to navigate the sustained heat exposure throughout their chosen endurance challenge.
Hell Mary has been a staple event in Watertown since its inception, offering various time divisions including six-hour, twelve-hour day and night runs, as well as twenty-four hour races for both rucking soloists and weighted vest categories. Participants who complete 100 miles at Hell Mary earn custom belt buckles that commemorate their achievement.
