Celebrated as one of the UK’s most picturesque half marathons, the Conwy Half Marathon takes runners on a 13.1-mile journey through the stunning landscapes of North Wales. The race commences on the quayside in front of the 700-year-old Conwy Castle, guiding participants along the Conwy River towards Deganwy and the West Shore of Llandudno. Runners then navigate around the Great Orme, enjoying panoramic views of the Isle of Anglesey, Puffin Island, and the North Wales coastline, before returning to Conwy for the finish. The 2025 race is set for November 16, starting at 9:30 AM. In addition to the main event, a free 1-mile Fun Run is available for all ages, starting at 8:45 AM. Given the race’s popularity and a participant cap of 3,000, early registration is recommended.
