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 22, 2026.

Common Questions About Running an April 5K in Delaware
What is a good 5K time?
Across the 5 of these April 5K races with published results from past editions, the median finisher ran 36:41, and the median winning time was 17:09. So anything under 36:41 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 April 5K field?
The median one finished 223 runners, across the 5 of these April 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 1:10:12.
