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 Sep 22, 2026.
When in October

By the numbers
The October Ultra races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
It is the fullest month of the year for the Ultra. October carries 45 of them, more than any other month, so you get the widest choice of dates, locations and course types without having to travel far for one.
The busiest weekend is October 10 and October 11, with 11 Ultra races on those two days, and the single busiest day is Saturday, October 10 with 10. Another 9 fall on a weekday, which is worth knowing if you are traveling for one.

The typical entry is $45, with paid entries running from $5 up to $200, and 4 that are free to enter. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
Across the 14 of these October Ultra races with published results from past editions, the median finisher ran 7:30:10, and the median winning time was 5:12:53. So anything under 7:30:10 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 50 runners, across the 14 of these October Ultra 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 10:44:55.
Texas has 5, New York has 4, Ohio has 4, New Jersey has 3, South Carolina has 3. If you are willing to travel, those are the states where an October weekend gives you the most to choose from.
