October Half Marathon Calendar event dates in dark grey are delinquent dates not updated by the race organizer yet. We strive to have dates 1 year out for October half marathons, but have no control of when they set, announce or update their dates.
October Half Marathons
The October Half Marathon Calendar is a complete simplistic listing of October half marathons 2020 in the USA. Currently the October half marathon schedule has 2020 half marathons, and October half marathons 2021 will be updated as they roll in from the 1/2 marathon race organizers. The October 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 October half marathon calendar features a complete listing of October half marathons in California, October half marathons in Texas, October half marathons in Colorado, October half marathons in New York, October half marathons in Utah, October half marathons in Illinois, October half marathons in Ohio, October half marathons in Florida, and all other 1/2 marathons in October across the USA.
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.
