About the race
Hell Hole Hundred is an ultramarathon set on the Jericho Horse Trail in the Francis Marion National Forest near Bethera, South Carolina. Races span from 10k up to 100 miles (including 25k, 50k, 50 mile, and a Night 25k option). Runners contend hot, humid summer swamp conditions as the course unfolds on dirt fire roads and single-track loops of about 16 and 18 miles, with three aid stations and well-marked routes.
Pacers are welcome for 50/100 mile distances. Primitive camping is allowed, and 100-mile finishers receive a custom buckle. The Swamp Series crowns overall champs across the three Francis Marion races. Visit the organization's website for the most recent information.
