Skyrunning at the Heart of Eryri
Events / Trail Running
Ogwen | Yr Helgi Du 2027
Take in the most spectacular views in Eryri's Ogwen Valley. With three distances available, covering some of the highest mountains in England and Wales as part of this imposing skyline, the Ogwen | Yr Helgi Du races include epic trails and technical terrain; they're truly mountain races.
The Carneddau are the Front Range of the Eryri (Snowdonia) mountains, rising from the North Wales coast to form the second highest mountains in the whole of England and Wales, with Carnedd Llywelyn being just 21m lower than it’s more famous cousin Yr Wyddfa (Snowdon). The 40K route also takes in the Glyderau range, adding another epic ridge line, and more ascent to the challenge!
This race provides an accessible skyline race that will test the experienced but also provide enough support to those looking to take their mountain running to the next level!
