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 Nov 12, 2026.

The busiest weekend in Florida is September 18 and September 19, with 6 of them, 5 of those on Saturday, September 18. One more falls on a weekday, which is worth knowing if you are traveling for it.
Across the 7 of these September 10K races with published results from past editions, the median finisher ran 1:02:22, and the median winning time was 49:33. So anything under 1:02:22 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.
The median one finished 8 runners, across the 7 of these September 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 1:33:32.
