Starting at 07:30

Organiser's Description

​A 50 mile ultra marathon, with a total height gain of 3000m, along coast, trail, mountain, river and forest in South Snowdonia, taking in a total of 15 peaks, including the whole of the iconic ridge-line and summit of Cadair Idris. This is a challenging, stunning route, and is at times remote.

Starting from Aberdovey, on the West coast of Wales, this is possibly Britain's most beautiful and least-traveled 50 mile ultra route. As well as covering sections of the Welsh Coastal Path, and the whole Cadair Idris ridge line, you will also summit several remote peaks around the Dyfi Estuary which is a UNESCO Biosphere Reserve. It is a beautiful part of Snowdonia, which you will come to realise on your 50 mile journey.
