Common Questions About Running a May 5K in New Jersey
What is a good 5K time?
Across the 11 of these May 5K races with published results from past editions, the median finisher ran 33:43, and the median winning time was 18:38. So anything under 33:43 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 May 5K field?
The median one finished 175 runners, across the 11 of these May 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 1:04:32.
