About average for North Carolina trail half marathons
The fastest quarter of the 2025 half marathon field finished under 2:14:13, against 2:13:15 in a typical North Carolina trail half marathon, 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.
Around October 24 the day usually runs from 47°F at dawn to 68°F in the afternoon, with measurable rain on about 16% of days. Cold snaps dip to 42°F and hot years reach 76°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.
