Comfortable temps, moderate wind

Starting at 60°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Moderate winds around 17mph may affect pacing on open sections of the course. Moderate humidity at 70% is worth noting for effort level, especially in later miles.

Race Info

The Kiawah Island Half Marathon covers 13.1 miles on the roads of Kiawah Island, South Carolina, and starts and finishes at the West Beach Conference Center in West Beach Village. Runners pass through maritime forest and along marsh views and neighborhoods of large island homes, with the route running east along Kiawah Island Parkway and Governors Drive, looping through the Flyway Drive area and returning to the beach side of the island. The course crosses the grounds of The Sanctuary hotel and is USATF-certified. It is held on the Saturday of race weekend with a combined start alongside the full marathon, and most of it lies inside a private community that is not open to the general public.
