About average for New York half marathons
The fastest quarter of the 2025 half marathon field finished under 1:52:24, against 1:54:19 in a typical New York 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 3 the day usually runs from 57°F at dawn to 69°F in the afternoon, with measurable rain on about 25% of days. Cold snaps dip to 49°F and hot years reach 75°F.
