OS Maps & ABP Southampton Marathon Partnership

The ABP Southampton Marathon is the city’s largest running event, sponsored by Associated British Ports, the UK’s second largest container terminal and largest deep sea gateway. Running enthusiasts can select one of four distances to run, a Full Marathon, Half Marathon, 10K and 5K. Our 2 lap racecourse, supported by the half and full route features Southampton’s unmissable landmarks, historical sites, waterfront and park views all within eyesight of the participants' event experience.

This year we are partnering with national mapping agency Ordnance Survey to deliver a streamlined representation of the route, combined with inclusive offers to make the ABP Southampton Marathon experience and other challenges accessible to you on an extended three month trial.

The official ABP Southampton Marathon Festival routes are now available on OS Maps. You may notice a slight difference in the displayed distance compared to the official race distance—this is due to how online mapping platforms calculate routes. We’re working on an update to make this clearer. Rest assured, all routes are professionally measured, and certification will confirm that runners complete the exact distance for their event.
