New Jersey Half Marathon

The New Jersey Half Marathon Calendar is a complete simplistic listing of New Jersey half marathons.  Currently the New Jersey half marathon schedule has 2020 New Jersey half marathons and 2021 New Jersey half marathons as they roll in. New Jersey half marathons 2020 & New Jersey 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 New Jersey half marathon calendar features a complete listing of Atlantic City half marathons, Trenton half marathons, Jersey City half marathons, Princeton half marathons, Mountainside half marathons, Morristown half marathons, Morris TWP half marathons, Ocean City half marathons, Ocean City half marathons, and many more 1/2 marathons in NJ.
