Common Questions About Running an October Ultra

Is October a good month for an Ultra?

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.

When in October are most Ultra races held?

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.

When should I sign up for an October Ultra?

As early as you can. 7 of these October Ultra races already have a price increase on the calendar, and 43 are open for entry right now. Another 2 have published an opening date and have not opened yet.

How much does an October Ultra cost to enter?

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.

What is a good Ultra time?

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.

How big is a typical October Ultra field?

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.

Which states have the most October Ultra races?

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.

Are there trail Ultra races in October?

Yes, 28 races around the United States get you off the pavement: 25 are trail races, and 3 mix road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.

Ultra Races in Other Months

September and November sit either side of October, which is where most people look next when a date does not fit.
