This event takes place over some of the most rugged terrain in Britain. There are significant risks of injury or loss which can arise from:

  • Steep and rocky ground (including cliffs and ravines) where a slip or fall could result in serious injury or death
  • Weather extremes (wind, precipitation or hot sun) leading to hypothermia or heat exhaustion
  • Crossings of major roads

Whilst the race organisers take all reasonable measures to ensure your safety, you must only enter this race with a full knowledge and understanding of the risks involved. All courses ascend the Gribin Ridge in the Ogwen Valley. Ascending this part of the route requires a head for heights and use of hands for support, it includes a grade 1 (the easiest grade) scramble and is waymarked.


There is a Bad Weather Course but this will only be implemented in the most extreme of circumstances and all competitors would be advised of this before the race start.
