Delaware Half Marathons

The Delaware Half Marathon Calendar is a complete simplistic listing of Delaware Half Marathons.  Currently the Delaware half marathon schedule has 2020 Delaware half marathons and 2021 Delaware half marathons as they roll in. Delaware half marathons 2020 & Delaware 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 (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 Delaware Half Marathon schedule features a complete listing of Wilmington half marathons, Rehoboth Beach half marathons, Newark half marathons, Lewes half marathons, Laurel half marathons, Dover half marathons, and any other 1/2 marathons in Delaware that arise.
