May Half Marathon Calendar - May Half Marathons 2027 and May Half Marathons 2028 as they Roll In

Search for your next May half marathon at the May Half Marathon Calendar USA website page. The half marathon running event calendar currently has May half marathons 2027 and May half marathons 2028 as they roll in.

For races that are late in posting their May half marathons, 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 to "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) the ability to plan their half marathon schedule, and plan travel well in advance. Half marathon events that update race dates super late, tend to have lower registration levels.

If you enjoy spring running, start planning your 2027 May half marathons, and your 2028 May half marathons as the new dates roll in. At Half Marathon Calendar USA, you can plan your half marathons by month, or search for half marathons by state. Half Marathon Calendar USA is a great simplistic half marathon listing for a quick and easy half marathon search.
