Route Description
Swim in Llyn Padarn in the shadow of Yr Wyddfa (Snowdon) surrounded by the history of Slate Mining in the Welsh hills.
Cycle alongside Yr Wyddfa, climbing up the famous Llanberis Pass. You’ll first cycle past the historic Dinorwic Slate Quarry and on through Nant Peris; as the climb really starts to burn you’ll be able to distract your mind with the incredible mountains that surround you. You turning point is the famous Pen y Gwryd Hotel where Hilary and Tenzing trained to take on Mount Everest. There's one final uphill struggle back to the top of Pen y Pass then it's down down down all the way back to Llanberis and transition with views all the way to Anglesey. The section from Nant Peris to Pen y Gwryd and back again is all on closed roads offering a once in a lifetime opportunity to cycle on the famous pass without traffic passing.
With so much history the tough 5.8 km run will have loads to keep you motivated as your legs complain. Running on some of the best trails around, you’ll go past Vivian Quarry, and head towards Dinorwic, before taking a short section of road in the direction of Fachwen. You’ll then turn steeply downhill through beautiful forests, with glimpses of Yr Wyddfa, past the Quarry Hospital and back along the home straight through the fields and to the finish line where a warm Always Aim High welcome will greet you.
