Swim Around Charleston

The Swim Around Charleston is a 19.3-kilometer (12-mile) open water race held annually in the Charleston Harbor, South Carolina. The event, scheduled for October 3, 2026, requires a solo entry fee of $425, which covers the logistics of managing a long-distance course through an active maritime channel. Swimmers navigate an 8-square-mile inlet defined by the junction of the Ashley and Cooper rivers, with the Wando River adding its own tidal influence to the harbor currents.

Historical currents and navigation

As you swim, the harbor floor tells a story of urban resilience. The route passes near areas affected by the 1838 Charleston fire, a disaster that decimated 150 acres and forced a total reconstruction of the city’s commercial core. While navigating the channel, swimmers pass the architecture of the post-1886 earthquake era; look for the distinct lion’s head bolts on surviving buildings like the Moses Levy Building, which were installed to reinforce walls after the city's seismic event. The shoreline also hosts the Kahal Kadosh Beth Elohim, one of the oldest Jewish congregations in the nation, and the historic St. Mary of the Annunciation, a site that has seen three successive church structures rise on its footprint. The harbor entrance itself remains protected by the natural barriers of Morris and Sullivan’s Islands, which help buffer the inland waters from the full force of the Atlantic tide. Participants receive a commemorative T-shirt, though the primary investment is in the support team required for this sustained effort through one of the American South's most significant deep-water ports.
