May 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 May half marathons, but have no control of when they set, announce or update their dates.

May Half Marathons

The May Half Marathon Calendar is a complete simplistic listing of May half marathons 2025 in the USA.  Currently the May half marathon schedule has 2025 half marathons, and May half marathons 2026 will be updated as they roll in from the 1/2 marathon race organizers. The May 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 May half marathon calendar features a complete listing of May half marathons in California, May half marathons in Texas, May half marathons in Colorado, May half marathons in New York, May half marathons in Utah, May half marathons in Illinois, May half marathons in Ohio, May half marathons in Florida, and all other 1/2 marathons in May across the USA.
