Hell Hole Hundred

The Hell Hole Hundred is an endurance event held within the Francis Marion National Forest, specifically on the Jericho Horse Trail near Bethera, South Carolina. Managed by Palmetto Ultras, the event takes place in a swamp environment characterized by high heat and humidity during the month of June.

The event offers several distance options to accommodate different goals:

  • 100 miles
  • 50 miles
  • 50k
  • 25k (Day and Night options)
  • 10k

The course is located outside of Charleston and primarily consists of a 16-mile loop and an 18-mile loop, depending on the chosen distance. The terrain features a mix of dirt fire roads and single-track trails. While the course is flat, the 10k distance is an out-and-back route without on-course aid stations. The trail is marked with blue reflective flags and ribbons, and participants are encouraged to use offline navigation tools as course markings may be affected by other forest users.

Three fully stocked aid stations are positioned along the course, providing water, sports drinks, soda, and various snacks. Port-a-potties are available at the start/finish area and at each aid station. Runners in the 50-mile and 100-mile categories may use pacers during the latter stages of their races. Due to insurance policies, dogs are not permitted on the course. All participants running during night hours are required to carry a light source.
