Siesta Half Marathon, 10K & 5K San Antonio, TX   Apr 26, 2026

The Siesta Half Marathon, 10K & 5K will take place on the River Walk, south. Starting in Mission Country Park, this course was certified in the past and coming back again.

Post covid, we are now allowed to move our races back into Bexar County. We loved having this race in Comfort, but now Siesta needs to return to Fiesta and get back to our San Antonio roots.

So if you are feeling a little overwhelmed with Fiesta Events this is a good chance to chill out with a great half marathon that runs on the San Antonio River, south. This out and back course will give you a chance to see your biggest competitors as they try to close in on you or you try to close in on them. The finish is the better than normal after party with a Fiesta Theme… no sleeping on the course, only after when you get home.
