Portsmouth Coastal Waterside Marathon Events 2026
The Portsmouth Coastal Waterside Marathon Events take place in December 2026 on the Southsea waterfront at S Parade, Portsmouth PO4 0SW. The programme offers a range of race distances along coastal routes that run around the shores of Langstone Harbour. The course is described as super flat and multi terrain, with some sections muddy in places. Final route maps will be released in November 2026 after confirmation with the Coastal Sea Defence team.
Race-day provisions include fully stocked aid stations, volunteer and spectator support, and festive finisher medals. Organisers offer official event merchandise in partnership with Scimitar Sports; pre-order options are available for technical running kit and keepsakes, and merchandise is sold separately from entry.
The event schedule includes options for runners seeking longer distances and those preferring shorter, festive runs. The organiser is Believe and Achieve Events Ltd and the event is presented as a winter coastal running weekend that showcases Portsmouth waterfront routes and seasonal atmosphere.
