Half Marathons in March 2027

March is when the spring half marathon calendar fills up. The NYC Half runs from Brooklyn into Manhattan, desert races make the most of the last cool weeks in Arizona and Southern California, and the Pacific Northwest starts racing again as the rain eases. If you're training for an April or May marathon, a March half is a well-timed tune-up.‍
