Common Questions About Running a May Half Marathon in Wisconsin
When should I sign up for a May Half Marathon?
As early as you can. 2 of these May Half Marathon races already have a price increase on the calendar, and 5 are open for entry right now. Another 1 have published an opening date and have not opened yet.
How much does a May Half Marathon cost to enter?
The typical entry is $22, with paid entries running from $12.99 up to $40. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
What is a good Half Marathon time?
Across the 3 of these May Half Marathon races with published results from past editions, the median finisher ran 2:06:46, and the median winning time was 1:07:40. So anything under 2:06:46 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 May Half Marathon field?
The median one finished 470 runners, across the 3 of these May 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 4:18:32.
