Michigan Half Marathon Calendar event dates in grey are delinquent dates not updated by the race organizer yet. We strive to have dates 1 year out for Michigan Half Marathons, but have no control of when they set, announce or update their dates.
Michigan Half Marathons
The Michigan Half Marathon Calendar is a complete simplistic listing of Michigan half marathons. Currently the Michigan half marathon schedule has 2026 Michigan half marathons and 2027 Michigan half marathons as they roll in. Michigan half marathons 2026 & Michigan half marathons 2027 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 Michigan half marathon calendar features a complete listing of MI half marathons, Detroit half marathons, Grand Rapids half marathons, Warren half marathons, Sterling Heights half marathons, Ann Arbor half marathons, Lansing half marathons, and many more 1/2 marathons in MI.
