About average for Illinois 5Ks
The fastest quarter of the 2026 5K field finished under 28:21, against 28:26 in a typical Illinois 5K, 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.
