For races that are late in posting their September half marathon date, we do our best to get those dates updated throughout the year, as race directors and race organizers update their websites. Updates can also be submitted via our easy "Submit or update a half marathon" button on our home page. We strive to update half marathon dates one year in advance, to allow out of state half marathon runners (and half marathon walkers) to be able to plan their half marathon schedule and plan travel well in advance. Half Marathon races that update their date super late, tend to have lower registration levels.
Fall running tends to be one of the most popular seasons for running half marathons. September half marathons are extra abundant across the upper mid-west and northern states, as well as the central states. There is also no shortage of half marathons in September in the southern states, but temperatures can still get substantially hot, which is not desirable for the average runner. September typically has the largest listing of half marathons, making it difficult to choose from well over 200 half marathons across the United States.

At Half Marathon Calendar USA, you can plan your half marathons by month, or search for half marathons by state.
