Terrain

Despite its location in the UK, the difficulty of this trek should not be underestimated as it requires you to trek through the night, with tough ascents and descents, with the added challenge of walking in the dark. The route is predominantly on good paths, but it's the variation of footpaths that makes this challenge a unique and fun experience. The famous ‘zig-zags’ contain several sections of loose scree that can be difficult when wet.


Food and drink

A celebration breakfast on Sunday morning is included in the cost however you are encouraged to bring some of your own preferred snacks to keep you going during the challenge. 

Please bring enough bottles to ensure you have 2 litres of water on you at all times. 

Please ensure you have had a substantial meal before arriving and that your water bottles are already filled.

  • Sustainability policy

This challenge should have a positive impact on the communities visited and is committed to sustainable and responsible tourism. It aims to make sure that impact on the local environment is minimised.

Summary

You can help achieve this goal by:

  • Adopting a policy of ‘leave no trace’.
  • Taking all litter off the trek with you, including fruit peels and skins.
  • Using public toilets when available and take any tissues from ‘wild wees’ home with you.
  • Stick to the footpaths at all times and avoid walking on their edges, to help prevent erosion from spreading.
  • Only using the car park(s) designated for your event, and not parking on the local streets.
  • Keeping noise to a minimum when passing houses in residential areas.
  • Leaving rocks, plants and other natural objects as you find them. Please don’t take these home with you.
  • Avoid transporting and introducing invasive species by cleaning your outdoor gear regularly.
  • Contributing to the local economy by paying for parking, staying an additional night in the local area or enjoying a local meal out.
  • Being patient and understanding if at points you have to wait or slow down due to others being on the same path.

You are asked to think carefully about any memorial-type activities you may plan for your challenge. It is fully appreciated that this challenge has emotional importance and encourages you to mark that special moment in your own way, whilst ensuring that the natural beauty and protection of the environment you’re in is maintained. Leaving photos or other memorabilia or writing on stones is contrary to the leave no trace principle.

Remember: ‘Take only memories, leave only footprints’.
