Conwy Half Marathon Entry, Date & Race Guide

The Conwy Half Marathon is one of the most scenic half marathons in the UK, set in the historic coastal town of Conwy in North Wales. Starting and finishing near Conwy Castle, the route follows the Conwy River before heading out along the coastline with views of the Irish Sea and the Great Orme.

The course is undulating rather than flat, with notable climbs around the Great Orme adding a challenge, but it remains a popular choice for runners looking for a rewarding and memorable race-day experience. Road closures and strong event organisation help create a smooth and enjoyable run.

With a limited field of around 4,000 runners, the race often sells out and attracts a mix of club runners, experienced racers, and first-time half marathoners. It’s well suited to those looking for a scenic alternative to flatter city races or as part of a build-up to a marathon.
