Montana Half Marathons

The Montana Half Marathon Calendar is a complete simplistic listing of Montana half marathons. Currently the Montana half marathon schedule has 2020 Montana half marathons and 2021 Montana half marathons as they roll in.  Montana half marathons 2020 & Montana half marathons 2021 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 Montana half marathon calendar features a complete listing of Bozeman half marathons, Whitefish half marathons, Great Falls half marathons, Victor half marathons, Baker half marathons, Billings half marathons, Red Lodge half marathons, West Yellowstone half marathons, Helena half marathons, Ennis half marathons, Stanford half marathons, Missoula half marathons, Condon half marathons, Kalispell half marathons, Ulm half marathons, Seeley Lake half marathons, and any other 1/2 marathons in MT.
