How fast is it?
About average for US half marathons
The fastest quarter of the 2025 half marathon field finished under 1:54:27, against 1:54:37 in a typical US half marathon, so times here are about average.
- 10K: Slower than most US 10Ks. The fastest quarter of the 2025 10K field finished under 56:24, against 54:18 in a typical US 10K, so times here run 4 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.
