New Hampshire 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 New Hampshire half marathons, but have no control of when they set, announce or update their dates.
The New Hampshire Half Marathon Calendar is a complete simplistic listing of NH half marathons. Currently the New Hampshire half marathon schedule has 2025 New Hampshire half marathons and 2026 New Hampshire half marathons as they roll in. New Hampshire half marathons 2025 & New Hampshire 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 New Hampshire Half Marathon calendar features a complete listing of Manchester half marathons, Nashua half marathons, Concord half marathons, Portsmouth half marathons, Hampton half marathons, Colebrook half marathons, and all other 1/2 marathons in New Hampshire.
