Common Questions About Running a January 10K

Is January a good month for a 10K?

January sits in the middle of the year for the 10K, carrying 272 against 694 in October and 92 in August. Enough to choose from, and easier to get into than the races at the peak of the season.

When in January are most 10K races held?

The busiest weekend is January 16 and January 17, with 75 10K races on those two days, and the single busiest day is Saturday, January 16 with 65. Another 23 fall on a weekday, which is worth knowing if you are traveling for one.

When should I sign up for a January 10K?

As early as you can. 81 of these January 10K races already have a price increase on the calendar, and 263 are open for entry right now. Another 9 have published an opening date and have not opened yet.

How much does a January 10K cost to enter?

The typical entry is $30, with paid entries running from $5 up to $500, 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 10K time?

Across the 117 of these January 10K races with published results from past editions, the median finisher ran 1:04:21, and the median winning time was 41:10. So anything under 1:04:21 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 January 10K field?

The median one finished 41 runners, across the 117 of these January 10K 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 1:44:57.

Which states have the most January 10K races?

California has 48, Florida has 41, Texas has 38, Colorado has 11, Georgia has 10. If you are willing to travel, those are the states where a January weekend gives you the most to choose from.

Are there trail 10K races in January?

Yes, 11 races around the United States get you off the pavement: 7 are trail races, and 4 mix road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
