Common Questions About Running an August 5K
When in August are most 5K races held?
The busiest weekend is August 7 and August 8, with 51 5K races on those two days, and the single busiest day is Saturday, August 7 with 40. Another 6 fall on a weekday, which is worth knowing if you are traveling for one.
When should I sign up for an August 5K?
As early as you can. 74 of these August 5K races already have a price increase on the calendar, and 83 are open for entry right now. Another 80 have published an opening date and have not opened yet.
How much does an August 5K cost to enter?
The typical entry is $30, with paid entries running from $5 up to $55, and 1 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 111 of these August 5K races with published results from past editions, the median finisher ran 35:16, and the median winning time was 18:24. So anything under 35:16 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 August 5K field?
The median one finished 130 runners, across the 111 of these August 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 1:05:49.
Which states have the most August 5K races?
Texas has 15, Florida has 12, California has 11, Colorado has 9, Michigan has 9. If you are willing to travel, those are the states where an August weekend gives you the most to choose from.
Are there trail 5K races in August?
Yes, 6 races around the United States get you off the pavement: 3 are trail races, and 3 mix road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
5K Races in Other Months
July and September sit either side of August, which is where most people look next when a date does not fit.
