9 Ultra races in September 2026
By the numbers
The September Ultra races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
It is a lean month for the Ultra. September carries 9, against 45 in October and 4 in August, the quietest. A September race is worth planning around rather than picking late, because the one that fits your training block may be the only one within reach.
The busiest weekend is September 26 and September 27, with 7 Ultra races on those two days, and the single busiest day is Saturday, September 26 with 6. Another 2 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 1 of these September Ultra races already have a price increase on the calendar, and 6 are open for entry right now. Another 3 have published an opening date and have not opened yet.
The typical entry is $76, with paid entries running from $20 up to $175. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
Yes, 6 races around the United States get you off the pavement: 6 are trail races. Surfaces are not always published, so it is worth checking a specific race before you register.
August and October sit either side of September, which is where most people look next when a date does not fit.
