Common Questions About Running an April Half Marathon in Michigan
How much does an April Half Marathon cost to enter?
The typical entry is $22, with paid entries running from $22 up to $35. 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 5 of these April Half Marathon races with published results from past editions, the median finisher ran 2:13:17, and the median winning time was 1:24:57. So anything under 2:13:17 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 April Half Marathon field?
The median one finished 63 runners, across the 5 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 3:30:18.
