Saturday 3rd October - Sunday 4th October 2026

Tackle one of the toughest 24-hour challenges in the UK as you summit all 15 of the highest peaks in Wales in a single epic push through Eryri National Park.

You’ll traverse three legendary mountain massifs in one continuous adventure:

• Snowdon Massif – Crib Goch, Garnedd Ugain, Snowdon

• Glyderau – Elidir Fawr, Y Garn, Glyder Fawr, Glyder Fach, Tryfan

• Carneddau – Pen yr Ole Wen, Carnedd Dafydd, Yr Elen, Carnedd Llewelyn, Foel Grach, Garnedd Gwenllian, Foel-fras

This is a true test of physical endurance, mental resilience, navigation, and mountain craft. From the exposed ridges of Crib Goch to the vast Carneddau plateau, every step builds toward an unforgettable achievement — one that very few people ever complete.

It’s the perfect stepping stone for those dreaming of the National 3 Peaks, Bob Graham Round, or any serious 24-hour mountain challenge. The sense of accomplishment when you finish the final peak, medal around your neck and certificate in hand, is absolutely worth every ounce of effort.
