How fast is it?

Slower than most Texas 5Ks

The fastest quarter of the 2026 5K field finished under 31:18, against 30:02 in a typical Texas 5K, so times here run 4 percent slower.

  • Half Marathon: Slower than most Texas half marathons. The fastest quarter of the 2026 half marathon field finished under 2:10:00, against 2:01:59 in a typical Texas half marathon, so times here run 7 percent slower.
  • 10K: About average for Texas 10Ks. The fastest quarter of the 2026 10K field finished under 56:14, against 57:11 in a typical Texas 10K, so times here are about average.

Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.
