The Cybi Coastal Marathon is considered to be one of the most scenic and challenging races. It runs alongside the Cybi25K, a 25K race.

Cybi Coastal Marathon Route
Starting in Holyhead, runners follow a multi-terrain course, including paths, tracks, beaches and coastline of the Welsh national/Anglesey Coastal Path.

The route includes many challenging sections. Depending on the weather, it can be very muddy, so trail shoes are highly recommended. Similarly, according to weather conditions, organisers may implement minimum kit requirements.
