Siesta Half Marathon 2027

The Siesta Half Marathon is a daytime race in San Antonio, based at Mission County Park on Padre Drive. It offers three distances: a half marathon, 10K, and 5K, so runners can choose anything from a short run to the full 13.1-mile distance. The races are part of the Texas Hill Country race series. The course runs along the riverwalk south of Mission County Park, keeping the route tied to the San Antonio River area rather than city streets alone. Registration includes a technical shirt in men's or women's sizing, plus snacks and adult beverages after the run. The event is pitched as a Fiesta-season run, with the name playing off the idea of kicking off Fiesta with a Siesta.
