Common Questions About Running an August 10K in Texas
What is a good 10K time?
Across the 12 of these August 10K races with published results from past editions, the median finisher ran 1:13:03, and the median winning time was 40:36. So anything under 1:13:03 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 10K field?
The median one finished 63 runners, across the 12 of these August 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 1:51:12.
