The Dirt Dash Marathon, Half Marathon, 10K & 5K

Saturday, October 12, 2024 • Johns Island, SC

Note: This race was known as the Frances Marion Dirt Dash prior to 2018. Pre-2018 info is still archived on that page.

Nestled among the lush pine forests and swamps and marshes filled with wildlife inside the Johns Island County Park that lies just to the southwest of Charleston here along the South Carolina coast, Johns Island plays host to the annual late-fall Dirt Dash Marathon, Half Marathon, 10K & 5K.

A race that takes runners along the wooded trails inside the park, the half marathon and the 5K take runners and walkers on a tour of a 738-acre park that plays host to horseback riders, runners, and even an archery range. Runners will get a chance to check out the archery range during packet pickup, which takes place near the range. Camping options are also available near the range for runners who wish to camp the night before the race.

With seven hours to finish all the races, walkers are welcome in the half marathon, and all finishers receive a finisher’s medal. There are also awards for the top five in each age group and the youngest and oldest runner in each race.
