The Swamp Fox Ultra

The Swamp Fox Ultra : March 7-8, 2026

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

• 100 Miler (about 104 miles)
• 50 Miler (about 53 miles)
• 50K
• Half Marathon (about 14 miles)
• 10K

The 52 mile out-and-back section forms the spine of the course used by longer distances; each distance runs to a designated turnaround and returns to the Buck Hall start/finish area. The terrain is mostly flat and runnable with single and double track, some fire roads, boardwalks, roots, and both shaded and open sections. Some lowcountry sections can hold water; boardwalks cross the wettest spots. The course is marked with flagging, signage, white blazes on the Swamp Fox Trail, and mile markers. A GPX file will be available in the runner guide and offline navigation is advised where service is poor.

Aid support includes four aid stations plus three water drops along the 52 mile out-and-back; most aid stations will be stocked with snacks, hydration options, heavier evening food for longer events, and porta potties. The event is cupless; participants receive a reusable collapsible cup at packet pickup. Drop bags may be transported to aid stations and returned to the start/finish. Pacers may join 50 and 100 mile runners at halfway or later, and crew access is allowed at aid stations. Required gear for 100 milers includes a phone with the course GPX, capacity to carry 1.5 L fluids, an emergency blanket, a lightweight jacket, and a power bank; required gear will be checked at the start/finish. The Swamp Fox Ultra is part of a Swamp Series spanning three races in the Francis Marion Forest. Camping is available at the Buck Hall overflow parking area.
