Half Marathons in May 2027

May half marathons move north and into the cities. The Run Like a Girl in Bellingham, Denver's Colfax Half runs the city's longest street at a mile high, and scenic destination halves pop up across the Rockies and the Pacific Northwest. Start early and the mornings are still cool enough to race hard.‍

‍Racing in May? Start our 12-week half marathon training plan around late February.
