The Swamp Fox Ultra

The Swamp Fox Ultra is a trail running event in McClellanville, South Carolina, held on sections of the Palmetto Trail through the Francis Marion National Forest. Courses use out and back routing across the Awendaw and Swamp Fox passages and start and finish at Buck Hall Recreation Area.

Distances offered:

  • 100 mile around 104 miles; out and back across the full Swamp Fox Passage.
  • 50 mile approximately 53 miles; out and back to a fire road turnaround.
  • 50K out and back on the same trail system.
  • Half marathon roughly 14 miles out and back.

The 52 mile out and back section of trail includes four staffed aid stations plus three water drops; most aid stations are reached twice on the longer courses. Aid stations provide snacks, hydration mixes, some hot and heavier food during the afternoon, and porta potties. The event operates a cupless policy; runners receive a reusable collapsible cup at packet pickup for use on course.

The 100 mile distance has mandatory on‑person gear requirements including a phone with the GPX file, capacity to carry 1.5 liters of fluid, an emergency blanket, a lightweight jacket, and a power bank. Tracking is included for 100 mile entrants; 50 mile runners may purchase tracking. Free primitive camping is available in the overflow parking at Buck Hall. The race is organized by Palmetto Ultras and is operated under a special use permit with the Francis Marion National Forest. Visit the organization's website for the most recent information.
