Common Questions About Running a January 5K in Illinois

When in January are most 5K races held?

The busiest weekend in Illinois is January 30 and January 31, with 3 5K races on those two days, and the single busiest day is Saturday, January 30 with 3. Another 1 fall on a weekday, which is worth knowing if you are traveling for one.

When should I sign up for a January 5K?

As early as you can. 3 of these January 5K races already have a price increase on the calendar, and 9 are open for entry right now.

How much does a January 5K cost to enter?

The typical entry is $30, with paid entries running from $22 up to $55. 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 3 of these January 5K races with published results from past editions, the median finisher ran 35:38, and the median winning time was 18:23. So anything under 35:38 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 5K field?

The median one finished 172 runners, across the 3 of these January 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 1:08:05.
