Common Questions About Running a May Half Marathon in Texas
What is a good Half Marathon time?
Across the 12 of these May half marathons with published results from past editions, the median finisher ran 2:23:52, and the median winning time was 1:34:21. So anything under 2:23:52 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 May Half Marathon field?
The median one finished 86 runners, across the 12 of these May half marathons 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 3:35:59.
