Welcome to the official site of the Portsmouth Coastal Waterside Marathon. This will be the 10th year for the Portsmouth Coastal Waterside Marathon, AND WE PLAN TO HAVE A PARTY. If you like to run something slightly different just before Christmas then this is for you. Full Marathon running from South Parade Pier to the end of the Hayling Billy Line and return. A unique multi terrain marathon with some fantastic views across Langstone Harbour.
Don’t fancy a marathon? Then you can go abit more and do the 50k ultra or for those who just want to be part of the festive celebrations try the festive half.
