Maryland 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 Maryland half marathons, but have no control of when they set, announce or update their dates.

The Maryland Half Marathon Calendar is a complete simplistic listing of Maryland half marathons. Currently the Maryland half marathon schedule has 2020 Maryland half marathons and 2021 Maryland half marathons as they roll in. Maryland half marathons 2020 & Maryland 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 Maryland half marathon calendar features a complete listing of MD half marathons, Baltimore half marathons, Columbia half marathons, Frederick half marathons, Annapolis half marathons, Germantown half marathons, Gaithersburg half marathons, and many more 1/2 marathons in MD.
