Wyoming Half Marathons
The Wyoming Half Marathon Calendar is a complete simplistic listing of Wyoming half marathons. Currently the Wyoming half marathon schedule has 2024 Wyoming half marathons and 2025 Wyoming half marathons as they roll in. Wyoming half marathons 2024 & Wyoming half marathons 2025 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 Wyoming half marathon calendar features a complete listing of Jackson half marathons, Laramie half marathons, Casper half marathons, Worland half marathons, Jackson Hole half marathons, Mountain View half marathons, Lander half marathons, Thayne half marathons, Green River half marathons, Wilson half marathons, Pinedale half marathons, and all other 1/2 marathons in WY.
