August 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 August half marathons, but have no control of when they set, announce or update their dates.
August Half Marathons
The August Half Marathon Calendar is a complete simplistic listing of August half marathons 2024 in the USA. Currently the August half marathon schedule has 2024 half marathons, and August half marathons 2025 will be updated as they roll in from the 1/2 marathon race organizers. The August 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 August half marathon calendar features a complete listing of August half marathons in California, August half marathons in Texas, August half marathons in Colorado, August half marathons in New York, August half marathons in Utah, August half marathons in Illinois, August half marathons in Ohio, August half marathons in Florida, and all other 1/2 marathons in August across the USA.
