Montana Half Marathons

The Montana Half Marathon Calendar is a complete simplistic listing of Montana half marathons. Currently the Montana half marathon schedule has 2022 Montana half marathons and 2023 Montana half marathons as they roll in.  Montana half marathons 2022 & Montana half marathons 2023 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.
