The Mitja Marató de Barcelona is a half marathon through Barcelona, with a field capped at 16,500 runners. The race requires a mandatory timing chip and attracts both experienced runners and individuals attempting the distance for the first time in Barcelona.
The route follows city streets, not a trail or closed stadium loop, offering 21.1 km within Barcelona. Participants come from abroad and locally. Registration is managed online or at selected Barcelona running shops. Wheelchair athletes have a separate email registration process. Race numbers are collected before race day at the Municipal Sports Center Estació del Nord.
