The busiest weekend in Pennsylvania is December 5 and December 6, with 15 5K races on those two days, and the single busiest day is Saturday, December 5 with 12. Another 4 fall on a weekday, which is worth knowing if you are traveling for one.
When should I sign up for a December 5K?
As early as you can. 21 of these December 5K races already have a price increase on the calendar, and 32 are open for entry right now. Another 2 have published an opening date and have not opened yet.
How much does a December 5K cost to enter?
The typical entry is $30, with paid entries running from $15 up to $46, and 2 that are free to enter. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
What is a good 5K time?
Across the 16 of these December 5K races with published results from past editions, the median finisher ran 32:24, and the median winning time was 18:18. So anything under 32:24 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 174 runners, across the 16 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 1:01:05.
Are there trail 5K races in Pennsylvania in December?
Yes, one race around Pennsylvania gets you off the pavement: 1 mixes road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
