The Swamp Fox Ultra

The Swamp Fox Ultra is a trail running event in McClellanville, South Carolina that uses passages of the Palmetto Trail to traverse the Francis Marion National Forest. Distances offered include:

  • 100 mile roughly 104 miles, out and back across the forest
  • 50 mile approximately 53 miles with a staffed turnaround access point
  • 50K single out and back on marked trails
  • Half Marathon out and back with a water drop at the turnaround

The course is described as mostly flat and runnable, comprised of single and double track trails, some fire roads, and boardwalks over wet areas. Much of the route is shaded; sections on fire roads are more open and lowcountry conditions may produce water on the trail. The Swamp Fox Trail section is marked with white blazes and mile markers; additional race marking and a GPX file are provided in the runner guide.

Aid and logistics details: four aid stations plus three water drops are positioned along the 52 mile out segment and will be encountered twice on the out and back, except at the turnaround. Aid stations provide food, hydration, and porta potties. The event has moved to a cupless policy; runners receive a reusable collapsible cup. Drop bags may be transported to aid stations.

Additional notes include required gear lists for 100 mile entrants, tracking provided for 100 mile runners, pacer and crew rules, volunteer credit for race entry, primitive camping at Buck Hall overflow parking, and awards for finishers.
