Common Questions About Running a December 5K in Oregon
What is a good 5K time?
Across the 5 of these December 5K races with published results from past editions, the median finisher ran 35:37, and the median winning time was 18:06. So anything under 35:37 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 December 5K field?
The median one finished 119 runners, across the 5 of these December 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 1:03:03.
