Maine Half Marathons
The Maine Half Marathon Calendar is a complete simplistic listing of Maine half marathons. Currently the Maine half marathon schedule has 2025 Maine half marathons and 2026 Maine half marathons as they roll in. Maine half marathons 2025 & Maine 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 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 Maine Half Marathon schedule features a complete listing of Portland half marathons, Lewiston half marathons, Bangor half marathons, Augusta half marathons, Bar Harbor half marathons, Brunswick half marathons, and all other 1/2 marathons in Maine.
