46 upcoming half marathons found · 16 with finish-time stats
San Antonio races tend to start and finish where the city's running life already clusters - around the River Walk, the Pearl district, and the corridors linking Brackenridge Park to the Broadway and Alamo Heights neighborhoods. That social, inclusive culture carries into race day: you will see all paces at the start line, and a brewery patio or coffee shop is rarely far from the finish.
The city's terrain runs the full spectrum, from flat riverfront paths in the urban core to the Hill Country-flavored trails at places like Eisenhower Park and McAllister Park on the northern edge. That variety shows up across the race calendar here, so whether you want something easygoing and paved or something that earns its elevation, San Antonio has an entry worth considering.

We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 16, 2026.
Across the 5 RunSignup half marathon editions in San Antonio with published results on RunSesh - walkers and charity entrants included - the median finish time was 2:25:30. The median winner crossed in 1:39:36, and the median last finisher took 3:35:18. Fields at these races had a median size of 73 runners, so you will not be lost in a crowd.
Fall (September to November) is the busiest stretch, with 16 races on the calendar. Winter (December to February) is next with 13. If you want the widest choice, fall gives you the most options. April is the quietest month of all, with just 1 race.
39 of the 43 races here say they give a shirt. Of the remaining 4, three have not published any giveaway details at all, so silence does not mean no shirt - it just means they have not said. None of the races in this group have confirmed a finisher medal.
The median field size across races with published results here is 73 runners, which is an approachable, non-intimidating environment. Finish times in those same races ranged widely - a median last finisher at 3:35:18 - so you will not be alone at the back of the pack. The flat riverfront and park routes that shape many San Antonio courses also tend to be forgiving for first-timers.
Yes, one race around San Antonio gets you off the pavement: 1 is a trail race.
