Snowdonia Sea2Sky Ultra 2027
September 5, 2027
Take on an Ultra Marathon. Change Childhoods.

Are you ready for your biggest challenge yet?
In September 2027, we’re looking for one determined runner to take on the incredible Snowdonia Sea2Sky Ultra Marathon and raise vital funds for Children North East.
This spectacular 54km trail race starts on the shores of Barmouth Beach before heading deep into the stunning landscapes of Eryri (Snowdonia) National Park. Along the way, you’ll climb to the summit of Cadair Idris before returning to the coast, completing an unforgettable journey that will test your endurance, resilience and determination.
But this challenge is about more than crossing the finish line.
Every pound you raise will help Children North East provide life-changing support to babies, children, young people and families across our region, helping them to improve their mental health, strengthen relationships and build brighter futures.
The Challenge
- 54km trail ultra marathon
- Eryri (Snowdonia) National Park
- First weekend of September 2027 (date TBC)

Whether you’re an experienced marathon runner looking for your next goal or a seasoned trail runner ready for a new adventure, this challenge offers the chance to achieve something extraordinary while making a real difference.
What Could Your Fundraising Achieve?
