How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 18, 2026.

Common Questions About Running a January 5K in Ohio
What is a good 5K time?
Across the 3 of these January 5K races with published results from past editions, the median finisher ran 33:56, and the median winning time was 19:00. So anything under 33:56 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.
How big is a typical January 5K field?
The median one finished 89 runners, across the 3 of these January 5K races with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 1:05:24.
