What the field actually runs
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 Oct 16, 2026.
By the numbers
The half marathons that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
Which weekends are busiest, what the fields run, and every Half Marathon on the calendar, one month at a time.
The pace per mile for every Half Marathon finish time, and mile splits plus training paces for the goal times runners chase most.
Across the 1,387 Half Marathon editions on RunSesh with published results, the median finisher ran 2:12:42, and the median winning time was 1:29:18. So a Half Marathon under 2:12:42 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.
Almost certainly not. In a typical Half Marathon on RunSesh the last recorded finisher came in around 3:23:51, well over an hour behind the median of 2:12:42. Real fields have a long tail of walkers and run-walkers behind the middle of the pack, and they are far slower than most first-timers expect.
The median Half Marathon on RunSesh finished 50 runners, across 1,387 editions with published results. Most half marathons are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field.
Yes, 108 races around the United States get you off the pavement: 74 are trail races, and 34 mix road and trail.
November is the busiest month for half marathons, with 439 of the 2,944 upcoming. If your training block is flexible, aiming at the busiest month gives you the most races to pick from and the best chance of finding one close to home.
