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 Jul 27, 2026.
By the numbers
The Ultra races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
Across the 81 Ultra editions on RunSesh with published results, the median finisher ran 6:38:19, and the median winning time was 4:26:31. So an Ultra under 6:38:19 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 Ultra on RunSesh the last recorded finisher came in around 9:28:46, well over an hour behind the median of 6:38:19. 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 Ultra on RunSesh finished 38 runners, across 81 editions with published results. Most Ultra races are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field.
Yes, 106 races around the United States get you off the pavement: 93 are trail races, and 13 mix road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
The typical Ultra entry on RunSesh is $49.99, with paid entries running from $10 up to about $9999, and 12 Ultra races that are free to enter. 110 of them already have a price increase scheduled, so entering early is almost always the cheaper option.
October is the busiest month for Ultra races, with 40 of the 197 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.
