Slower than most Texas trail half marathons
The fastest quarter of the 2026 half marathon field finished under 2:40:13, against 2:27:50 in a typical Texas trail half marathon, so times here run 8 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 27 the day usually runs from 58°F at dawn to 82°F in the afternoon, with measurable rain on about 15% of days. Cold snaps dip to 46°F and hot years reach 89°F.
Based on 75 days within a week of the date over the last 5 years, from historical weather for the start area. Not a forecast.
