Iowa Half Marathons
The Iowa Half Marathon Calendar is a complete simplistic listing of Iowa half marathons. Currently the Iowa half marathon schedule has 2025 Iowa half marathons and 2026 Iowa half marathons as they roll in. Iowa half marathons 2025 & Iowa half marathons 2026 also identify trail half marathons and walker friendly half marathons by a (T) symbol and a (W) symbol. The (T) means it is a TRUE trail half marathon (off road, switchbacks, etc) and a (W) means it is truly "official walker friendly" requiring the half marathon to allow a minimum of 18:32 mile pace, minimum 4 hours for participants to finish the 13.1 mile distance.
The Iowa half marathon schedule features a complete listing of Des Moines half marathons, Cedar Rapids half marathons, Cedar Falls half marathons, Council Bluffs half marathons, Dubuque half marathons, Iowa City half marathons, Waterloo half marathons, Marion half marathons, and many more 1/2 marathons in Iowa.
