9th May 2026. 24 Hours. 10 Climbs. £350 minimum.
Did you know?
Pen y Fan stands at 2,907 ft and Mount Everest reaches 29,029 ft, which means if you complete 10YFan, you’ll have climbed the equivalent height of Everest itself. Pretty incredible, right?
It really puts into perspective just how huge the challenge is. But the good news? You won’t need oxygen tanks, snow boots or a tent, just the determination to see how many climbs you can conquer in 24 hours. No pressure, just pure personal achievement.
10YFan is for everyone.
Whether you complete a single climb or power through all ten, every ascent is an amazing accomplishment.
And when you choose to support Cardiff & Vale Health Charity, our team will be right there with you, cheering you on, helping with your fundraising, and making sure your 10YFan experience is something truly unforgettable.
The challenge begins in the early evening and runs for a full 24 hours, taking you through the night and into sunrise. You’ll get to experience Pen y Fan as few ever do, from star‑filled skies (weather willing!) to the break of dawn over the Beacons.
