Idaho Half Marathons
The Idaho Half Marathon Calendar is a complete simplistic listing of Idaho half marathons. Currently the Idaho half marathon schedule has 2023 Idaho half marathons and 2024 Idaho half marathons as they roll in. Idaho half marathons 2023 & Idaho half marathons 2024 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 21k (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 Idaho half marathon calendar features a complete listing of Boise half marathons, Idaho Falls half marathons, Nampa half marathons, Meridian half marathons, Pocatello half marathons, Caldwell half marathons, Coeur d'Alene half marathons, Twin Falls half marathons, Lewiston half marathons, and many more 1/2 marathons in ID.
