Over Snowdon and through the Snowdon Massif in alpine-scale style
Other trail races within 199 miles
The UTS 50K is a 56km loop from Llanberis that includes a full ascent of Yr Wyddfa (Snowdon), the highest peak in Wales, before threading through the rugged trails of the Snowdon Massif. With 3,400m of elevation gain packed into 56km, the terrain ranges from runnable valley sections to highly technical mountain trails featuring rocky slabs and narrow exposed ridgelines. Positioned as the perfect stepping stone into alpine-scale ultra-trail running, the UTS 50K is deceptively demanding.
