July 4th Run 5K/10K/13.1 SAN ANTONIO

The Merry Christmas Run in San Antonio is a holiday run held at Olmos Basin Park, offering 5K, 10K, and half-marathon distances, along with a Family 1 Mile Fun Run. Starts are staggered throughout the morning. The event is organized more like a small group run than a large city race, with capped waves that close once full. Runners and walkers of all paces are welcome, and guardians must accompany anyone under 18. The course map is sent to participants via email, so public details emphasize the event's format rather than specific route landmarks. Timing is optional and not chip-based; participants can use an app to track their own time, submit it, or request assistance from coordinators. Registration typically includes a running shirt, but an eco-registration option is available, forgoing the shirt at a reduced price. A virtual option or wait list is offered when in-person waves are full.
