Siesta Half Marathon, 10K and 5K : Mission County Park, San Antonio

The event offers multiple running options that use an out-and-back course along the San Antonio River, south of the city. The course starts at Mission County Park on Padre Drive and was certified in the past; the organizers have restored this route for the event.

Distances and formats include:

  • Half marathon (13.1 miles)
  • 10K
  • 5K
  • 0.05K fun run
  • Virtual options for several distances
  • 5K walk-only option

Packet pickup is available at Fleet Feet San Antonio Culebra Commons the day before the event and on race morning at the start line. Awards are given 1st to 4th in five-year age increments across the half marathon, 10K and 5K. Age categories run from 14 and under through 90 plus. Overall awards for first, masters and super masters will be based on gun time; age-group awards use chip time because of wave starts.

Additional event notes: no dogs are allowed on the course. Shirt size is not guaranteed for late sign-ups but will be ordered if unavailable. A 50% discount applies automatically for participants 16 and younger and for those 70 and older; combining other discount codes with this reduction will result in cancellation. There are no refunds. Transfer fees apply for entry changes before the race; no transfers after race day. Visit the organization's website for the most recent information.
