The Swamp Fox Ultra

March 7th 2026
McClellanville, SC
50 KM | 50 Miles | 105 Miles

Welcome to the Swamp Fox Ultra presented by Fleet Feet and Billy Simons Real Estate under management of Palmetto Ultras! We have some NEW updates to the course that we're really excited about this year

Embark on a truly unparalleled trail racing experience, as our event is the only trail race (that we know of at least) that spans across the entire Francis Marion National Forest. While I do love a good looped course with the convenience of having gear and nutrition close at hand (and we offer a few of those), this race demands a bit more strategic planning to ensure you're well-equipped throughout. The reward? You'll run through 52 miles of breathtaking lowcountry trails before heading back to the start/finish line if you've decided to tackle the 100 mile distance. And even though you're heading back on the same trail, once the sun sets the trail takes on a whole new feel. 

50 mile, 50k, Half Marathon, and 10k runners will also run an out and back---no loops or repeated out and backs. This allows you to see more of the trails and provides an added element of adventure as you'll need to strategically plan what you're carrying with you.

Undertaking an adventure like this requires support, and in that spirit, we've bid farewell to drop bags in favor of strategically placed aid stations. My goal is simple: to see every participant cross the finish line, and I'm committed to providing the necessary support to make that happen. So, lace up your shoes, embrace the challenge, and let's make this an unforgettable journey through the heart of the Francis Marion National Forest.
