Trail Running  | Black Diamond Yr Wyddfa | Snowdon24 Ultra Trail 2025

Black Diamond Yr Wyddfa | Snowdon24 Ultra Trail 2025 Trail Running 24 hour

The challenge is to complete as many ascents and descents of Yr Wyddfa (Snowdon) as possible within the 24-hour period. The race winners will be the athletes who complete as many of these as possible.

If a runner begins a lap but does not complete it within the 24-hour period, it will NOT count towards the total for that runner or team. In the event of a tiebreak on the number of ascents and descents, the fastest will win!

To add to the excitement and motivation individuals, pairs and teams can set the goal of achieving one of the following awards. Awards will take the shape of a unique local slate that marks the highest level achieved.

  • 3 times ascend and descend – Yr Wyddfa Triple
  • 4 times ascend and descend - The Eiger Challenge
  • 5 times ascend and descend – The Mont Blanc Challenge
  • 6 times ascend and descend – The Kilimanjaro Challenge
  • 7 times ascend and descend - The Ama Dablam Challenge

  • 9 times ascend and descend - The K2 Challenge
  • 10 times ascend and descend – The ultimate Everest Challenge!
