Common Questions About Running an April Ultra

Is April a good month for an Ultra?

It is one of the busier months. April carries 28 Ultra races, against 45 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.

When should I sign up for an April Ultra?

As early as you can. 19 of these April Ultra races already have a price increase on the calendar, and 21 are open for entry right now. Another 7 have published an opening date and have not opened yet.

How much does an April Ultra cost to enter?

The typical entry is $40, with paid entries running from $10 up to $889, 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.

How big is a typical April Ultra field?

The median one finished 28 runners, across the 10 of these April 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 8:39:48.
