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 Nov 12, 2026.

Common Questions About Running a January 5K in Virginia
When in January are most 5K races held?
The busiest weekend in Virginia is January 16 and January 17, with 5 of them. Another 7 fall on a weekday, which is worth knowing if you are traveling for one.
What is a good 5K time?
Across the 14 of these January 5K races with published results from past editions, the median finisher ran 33:32, and the median winning time was 18:02. So anything under 33:32 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 192 runners, across the 14 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 1:05:41.
