  • Half Marathon: About average for New York half marathons. The fastest quarter of the 2026 half marathon field finished under 1:56:12, 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.
