The Experience
The Heatwave Half Marathon in San Antonio presents a unique summer running challenge, embracing the Texas heat with a vibrant atmosphere. This race is designed to be a family-friendly event, offering multiple distances including a 5K and 10K alongside the half marathon.
Runners can expect a fast, flat course, ideal for setting personal bests, on paved roads. The emphasis is on fun and participation, with chip timing, live results, and awards. Post-race, participants can cool down with complimentary ice cream, a welcome respite from the typical 77–98°F race-day temperatures.

For those unable to attend, a virtual race option allows runners to participate from anywhere while still receiving the event's signature gear. Youth pricing and a kids' dash further enhance its appeal as a community event.
