Previous Experience/Fitness

You will need to be a fit mountain fell runner. A head for heights is necessary. Do not under-estimate this challenge. Ascents and descents are demanding. Some ridges are exposed with steep drops. It is far more strenuous and requires more stamina than the National 3 Peaks Challenge.


You will need clothing and footwear that is appropriate for mountain walking conditions. A kit list, estimate timings, route information details will be provided on booking.

Look for the contact page link on the booking form to enquire about the dates and details of all upcoming activities and courses.

We are happy to arrange private guiding or instruction to suit requirements.
