Common Questions About Running a March 5K in New Jersey
What is a good 5K time?
Across the 10 of these March 5K races with published results from past editions, the median finisher ran 31:19, and the median winning time was 17:00. So anything under 31:19 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 March 5K field?
The median one finished 304 runners, across the 10 of these March 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 59:44.
