How fast is it?

Faster than most Texas trail 5Ks

The fastest quarter of the 2025 5K field finished under 29:48, against 33:44 in a typical Texas trail 5K, so times here run 12 percent faster.

  • 10K: Faster than most Texas trail 10Ks. The fastest quarter of the 2025 10K field finished under 52:56, against 1:02:12 in a typical Texas trail 10K, so times here run 15 percent faster.

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.
