Warm start, rising temps ahead

Runners will face temperatures starting at 68°F and climbing to 84°F by the finish. Winds will be light, averaging 10 mph from the SE, with occasional gusts up to 22 mph, but this should not significantly impact performance. Given the humidity at 65%, runners should consider adjusting their pace in the late laps as conditions heat up. Staying hydrated will be crucial throughout the race.

Race Info

Siesta Half Marathon is a half marathon with 10K and 5K options held each spring in San Antonio, Texas, starting and finishing at Mission County Park. The out-and-back course runs along the San Antonio River's Mission Reach, part of the city's River Walk system. ScallyWompus runs it as one leg of its Texas Hill Country race series and says the course was USATF-certified in an earlier edition before a hiatus.
