Take on the trails of Eryri
The Eryri 50K is set deep in the heart of Eryri (Snowdonia) National Park, North Wales. The race begins in Llanberis, and spans 56km with 3,400m+ of elevation gain.
From the outset, runners tackle steep terrain as the route includes an ascent of Yr Wyddfa (Snowdon), the highest peak in Wales and then threads through the rugged trails of the Snowdon Massif.
Terrain varies from runnable sections to highly technical mountain trails, with rocky slabs and narrow ridgelines. The route weaves through classic mountain scenery, including peaks, valleys, and ridges offering both challenge and beauty in equal measure. Eryri 50K acts as the perfect stepping stone into Alpine-scale mountain ultra-trail running.
