semi-marathon de Conwy 2026

The Conwy Half Marathon begins and ends on the bridge by the quayside, opposite Conwy Castle. This places runners alongside a 700-year-old landmark before they reach race pace. It is a 13.1-mile road half marathon held in Conwy, North Wales, typically in mid-November with a morning start. The participant limit is 4,000, and recent events have seen over 3,000 runners, creating a busy atmosphere without being overwhelmingly large. The route runs alongside the Conwy River, heading towards Deganwy and West Shore Llandudno, then proceeds along Church Walks towards Llandudno Pier. From there, participants circle the Great Orme counter-clockwise, with vistas of the Isle of Anglesey, Puffin Island, and the North Wales coast. The course is largely flat on broad roads, featuring some gradual inclines and descents, and approximately 327 metres of elevation gain. While parts are fast, it is not entirely flat. Runner's World readers recognized it as one of the UK's top five half marathons for scenery, and the event is now in its second decade.
