Hell Hole Hundred

The Hell Hole Hundred is an ultrarunning event on the Jericho Horse Trail within the Francis Marion National Forest, near Bethera, South Carolina. The races are scheduled for June 5–7, 2026.

The event offers multiple distances:

  • 100M
  • 50 Miler
  • 50K
  • 25k
  • Night 25k
  • 10k

The courses consist of a combination of 16-mile and 18-mile loops on dirt fire roads and single-track trail, described as flat. The 10k is an out-and-back course. The event is noted for taking place in a hot and humid swamp environment in June.

Three fully stocked aid stations will be available, including one at the start/finish line serving food and snacks. Porta potties will be located at the start/finish and aid stations. Primitive camping is available on-site from the night before the race until its conclusion, with no water or electric hookups.

All finishers receive a choice of a wooden coaster or glass. Top three male and female finishers in each distance receive a trophy. Registrants by a to-be-determined deadline receive a hat, and 100-mile finishers receive a custom buckle.

The event is part of a Swamp Series that includes three races in the Francis Marion Forest. Runners who complete distances at all three races are eligible for a King/Queen of the Swamp award based on total accumulated miles. Visit the organization's website for the most recent information.
