Common Questions About Running an October 5K in Maine
When should I sign up for an October 5K?
As early as you can. 8 of these October 5K races already have a price increase on the calendar, and 28 are open for entry right now. Another 1 have published an opening date and have not opened yet.
How much does an October 5K cost to enter?
The typical entry is $25, with paid entries running from $2 up to $90. 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 8 of these October 5K races with published results from past editions, the median finisher ran 37:40, and the median winning time was 19:23. So anything under 37:40 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 October 5K field?
The median one finished 99 runners, across the 8 of these October 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 1:08:23.
