2027 Siesta Half Marathon, 10K and 5k

The Siesta Half Marathon, 10K, and 5K are road races held in San Antonio, Texas. All three distances are part of the Texas Hill Country race series. The event takes place along the River Walk south of Mission County Park, offering participants a city route connected to San Antonio’s river corridor, rather than a remote trail or track. The race format accommodates various runner preferences on the same day: the half marathon for distance runners, the 10K as a mid-distance option, and the 5K for a shorter run. Registration provides a technical shirt in men's or women's sizing, along with snacks and adult beverages post-race.
