Slower than most Texas trail half marathons
The fastest quarter of the 2026 half marathon field finished under 2:49:12, against 2:27:50 in a typical Texas trail half marathon, so times here run 14 percent slower.
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.
Around March 13 the day usually runs from 51°F at dawn to 75°F in the afternoon, with measurable rain on about 19% of days. Cold snaps dip to 39°F and hot years reach 84°F.
