How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Sep 22, 2026.

The September 5K races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
Common Questions About Running a September 5K in Arkansas
When in September are most 5K races held?
The busiest weekend in Arkansas is September 26 and September 27, with 7 5K races on those two days, and the single busiest day is Saturday, September 26 with 7. Another 2 fall on a weekday, which is worth knowing if you are traveling for one.
When should I sign up for a September 5K?
As early as you can. 1 of these September 5K races already have a price increase on the calendar, and 6 are open for entry right now. Another 1 have published an opening date and have not opened yet.
How much does a September 5K cost to enter?
The typical entry is $20, with paid entries running from $10 up to $60. 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 7 of these September 5K races with published results from past editions, the median finisher ran 31:26, and the median winning time was 17:16. So anything under 31:26 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 September 5K field?
The median one finished 73 runners, across the 7 of these September 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 1:00:51.
5K Races in Other Months
August and October sit either side of September, which is where most people look next when a date does not fit.
