Close
Probably the biggest trail marathon in the UK, the Snowdonia Trail Marathon is a challenge in every sense of the word. Ascending 1,685 metres over 27 miles of iconic and spectacular trails, this epic race will circumnavigate and eventually climb Wales' highest peak - Snowdon. The incredible route explores the trails, gorgeous panoramic views and tough climbs that make Snowdonia National Park such a mecca for outdoor enthusiasts. Visiting Rhyd Ddu, Beddgelert, Nant Gwynant, Pen y Pass and Snowdon (via the PyG Track to the Finger Stone) to then descend to the Finish Line via the Llanberis Path, there surely can't be a more striking trail marathon route in the UK!
