Step into the mountains with the Ogwen 15km, the perfect introduction to Mountain Running in Eryri. This stunning loop from Plas y Brenin takes you high over Gallt yr Ogof and along the sweeping ridge of Cefn y Capel, before descending back into the heart of the Ogwen Valley.

With nearly 700m of elevation packed into 15km of rugged trails, including the 805m summit of Foel Goch, this race delivers a true mountain running experience without the full ultra-distance commitment. Expect technical terrain, exhilarating ridge running, and panoramic views across the Carneddau and beyond.

Challenging, beautiful, and unforgettable – the Ogwen 15km is mountain racing at its most accessible.
