Introducing the most demanding and toughest event of the quarter series yet; The Snowdonia Quarter.

The Snowdonia Quarter ultra marathon boasts a breathtaking 50 mile route from the West coast of Wales, through the Snowdonia National Park, over Mount Snowdon to the North coast of Wales.

This Snowdonia ultra marathon can be undertaken as a solo, relay team of two, or relay of four.

The task is brutally simple: To run non-stop from Borth-y-Gest on the West coast of wales, to Conwy on the North coast of Wales. Not forgetting the relentless 3,329 ft ascent to the summit of Mount Snowdon and the undulation of the Snowdonia National Park. This is the ultimate trail runner's rush; with spectacular exposure, challenging terrain and an immense total ascent. Each participant must be prepared both mentally and physically for the tenacious challenge ahead.
