If you want a mountain challenge that will test your physical and mental resolve than you are in the right ball park. Some ridges are exposed with steep drops so a head for heights will be required. The ascents/descents are very strenuous so you will need to be "hill-fit". Note that it is far more strenuous and requires more stamina than the National 3 Peaks Challenge. We won't necessarily be running but we will be moving quickly over mountainous terrain with limited "rests".


The distance from the top of the first peak (Snowdon) to the last peak (Foel Fras) is around 38 km. Note with the walk-in to the first peak, and walk-out from the last peak added you should expect a total distance of 50km. The total height gain is just under 4000m.


Weather will happen. The impact that high winds, dense fog, persistent rain, cold, and heat can have on such a challenge is significant. In certain conditions it will take longer than planned, and in severe conditions we will re-sort to Plan B.
