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

Connecticut Half Marathons

The Connecticut Half Marathon Calendar is a complete simplistic listing of Connecticut half marathons. Currently the Connecticut half marathon schedule has 2022 Connecticut half marathons and 2023 Connecticut half marathons as they roll in. Connecticut half marathons 2022 & Connecticut half marathons 2023 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 Connecticut Half Marathon race calendar features a complete listing of Bridgeport half marathons, New Haven half marathons, Hartford half marathons, Stamford half marathons, Waterbury half marathons, Norwalk half marathons, Danbury half marathons, and all other 1/2 marathons in Connecticut.

A half marathon is 13.1 miles (or in kilometers is a 21k). We understand sometimes there will be a slight margin of error up or down when runners run or walk any race distance, however our calendar only is a listing for true half marathons that do all they can to measure their course as an official half marathon 13.1 mile / 21k distance.  Races that are not 13.1 miles, we encourage not to call their race a 1/2 marathon to lessen confusion for runners & walkers looking to participate in a true 1/2 marathon distance. Some runners don't care, but you'd be surprised how many that do.
