Ultra-Trail Snowdonia 50K (UTS 50K) by UTMB

Experience the untamed beauty and thrilling challenge of Eryri/Snowdonia National Park with the Ultra-Trail Snowdonia 50K (UTS 50K) by UTMB. Often described as a perfect initiation into the world of true mountain ultra-running, this race offers a formidable test of endurance, skill, and resilience over technical terrain, all within a 56km journey.

The Course

Don't let the "50K" distance fool you – the UTS 50K is a seriously tough mountain ultra. The race kicks off with an iconic and immediate ascent, taking runners up the majestic Yr Wyddfa (Snowdon), sharing the exhilarating start with the longer UTS distances. The route then plunges into a diverse mix of terrain, weaving through the rugged heart of Northern Snowdonia. You'll encounter everything from runnable sections to highly technical mountain trails, featuring rocky slabs, exposed ridgelines, and potentially boggy ground. This course is designed to challenge both your physical stamina and your mountain running proficiency, demanding careful foot placement and a strong mental game. It's the ideal stepping stone for aspiring ultra-runners looking for an authentic mountain experience or for seasoned trail runners seeking a demanding and rewarding challenge.

Your Path to the UTMB World Series 

As a proud event of the UTMB World Series, finishing the UTS 50K not only earns you bragging rights but also 2 Running Stones. These crucial Stones contribute to your eligibility for the coveted UTMB Mont-Blanc ballot, offering a pathway to the pinnacle of global trail running.
