Common Questions About Running an October 10K in Missouri
When should I sign up for an October 10K?
As early as you can. 7 of these October 10K races already have a price increase on the calendar, and 20 are open for entry right now. Another 1 have published an opening date and have not opened yet.
How much does an October 10K cost to enter?
The typical entry is $30, with paid entries running from $12.99 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 10K time?
Across the 6 of these October 10K races with published results from past editions, the median finisher ran 1:07:02, and the median winning time was 52:00. So anything under 1:07:02 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 10K field?
The median one finished 66 runners, across the 6 of these October 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 1:45:22.
Are there trail 10K races in Missouri in October?
Yes, one race around Missouri gets you off the pavement: 1 is a trail race. Surfaces are not always published, so it is worth checking a specific race before you register.
10K Races in Other Months
