The Welsh 3000s Challenge is the ultimate 24-hour mountain challenging, ascending all of Wales' 15 peaks over 3,000ft, with over 4,200 metres of ascent across 46 brutal kilometres! We begin at the crack of dawn with an early early ascent & traverse of Crib Goch - a classic, exposed Grade 1 scramble - en route to the summit of Snowdon, before traversing the rocky Glyderau and remote Carneddau ranges in a seriously arduous but ultimately exhilirating mountain adventure.
