Ogwen | Yr Helgi Du 2026 Trail Running 10k

The Ogwen 10 is the perfect opportunity to be part of the event and enjoy some stunning mountain views. The out-and-back, fast and flat route follows the historic Eryri Slate Trail through the Valley, with the Glyderau and Carneddau dominating the landscape.

It’s a perfect introduction to trail running and could serve well as a lovely double day if combined with the Snowman Swims or even help you to stay loose for the Triathlon/Duathlon the following day.
