Ogwen | Yr Helgi Du 2027

Set in the heart of Eryri (Snowdonia), Ogwen Yr Helgi Du is a serious mountain race that demands respect, preparation, and skill. This is not trail running. This is technical terrain, sustained climbing, and true mountain conditions.

At the centre of the event is the 40K Skyrace, an officially accredited International Skyrunning Federation (ISF)course. It features steep ascents, exposed ridgelines, and challenging navigation through some of the most iconic and rugged landscapes in North Wales. This distance is designed for experienced mountain runners who are confident moving efficiently across technical ground.

The 25K follows the same philosophy, offering a shorter but still demanding mountain experience. Expect steep climbs, rocky descents, and sections that require focus and mountain awareness throughout. This is a race for those who already have solid mountain running experience and want a high quality, challenging course.

For those looking to take the next step beyond trail running, the 15K provides a supported introduction to mountain racing. While still physically demanding, it is designed to help runners build confidence on more technical terrain, with clear routes and a strong safety presence throughout.

Ogwen Yr Helgi Du is about progression, challenge, and respect for the mountains. Whether you are racing at an international skyrunning level or stepping into mountain terrain for the first time, this event offers an authentic and uncompromising experience in one of the UK’s most spectacular settings.
