September 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 September half marathons, but have no control of when they set, announce or update their dates.
September half marathons 2027
September Half Marathons
The September Half Marathon Calendar is a complete simplistic listing of September half marathons 2027 in the USA. Currently the September half marathon schedule has 2027 half marathons, and September half marathons 2028 will be updated as they roll in from the 1/2 marathon race organizers. The September Half Marathon schedule identifies 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 September half marathon calendar features a complete listing of September half marathons in California, September half marathons in Texas, September half marathons in Colorado, September half marathons in New York, September half marathons in Utah, September half marathons in Illinois, September half marathons in Ohio, September half marathons in Florida, and all other 1/2 marathons in September across the USA.
