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 April
Half Marathon races do not spread evenly across April. The busiest weekend is April 10 and April 11, with 89 of them. Another 8 fall on a weekday.
By the numbers
The April Half Marathon races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
It is one of the busier months. April carries 275 Half Marathon races, against 523 in October, which is the fullest month of the year. There is a real choice of dates here, with less competition for entries than the peak of the season.
The busiest weekend is April 10 and April 11, with 89 Half Marathon races on those two days, and the single busiest day is Saturday, April 10 with 77. Another 8 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 88 of these April Half Marathon races already have a price increase on the calendar, and 253 are open for entry right now. Another 22 have published an opening date and have not opened yet.
The typical entry is $30, with paid entries running from $10 up to $100, and 1 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 123 of these April Half Marathon races with published results from past editions, the median finisher ran 2:14:35, and the median winning time was 1:23:40. So anything under 2:14:35 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 95 runners, across the 123 of these April Half Marathon 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 3:38:30.
Texas has 40, California has 31, Florida has 18, Colorado has 12, New Jersey has 11. If you are willing to travel, those are the states where an April weekend gives you the most to choose from.
Yes, 12 races around the United States get you off the pavement: 11 are trail races, and 1 mixes road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
March and May sit either side of April, which is where most people look next when a date does not fit.
