Missouri Half Marathon Calendar event dates in dark grey are delinquent dates not updated by the race organizer yet. We strive to have dates 1 year out for Missouri half marathons, but have no control of when they set, announce or update their dates.
Missouri Half Marathons
The Missouri Half Marathon Calendar is a complete simplistic listing of Missouri half marathons. Currently the Missouri half marathon schedule has 2025 Missouri half marathons and 2026 Missouri half marathons as they roll in. Missouri half marathons 2025 & Missouri 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 Missouri half marathon calendar features a complete listing of Kansas City half marathons, St. Louis half marathons, Columbia half marathons, Branson half marathons, St. Charles half marathons, Springfield half marathons, West Plains half marathons, and many more 1/2 marathons in MO.
