  • Who runs the Defeat the Peak challenges?

    For our Defeat the Peak series of events, we work with a challenge company called Charity Challenge. They have been operating challenges in the UK and overseas for 24 years and have an extensive safety management system in place for all their challenges. They prioritise the safety of participants, staff and support teams. Charity Challenge have operated both day and night challenges on Scafell Pike for many years and have a huge wealth of experience.

    Our Defeat the Peak challenges are led by their hugely experienced challenge leaders who all hold the summer Mountain Leader qualification or higher. They use a high ratio of leaders to participants, which increases for our night challenges. All events are risk assessed and all leaders are in communication with each other on the challenge via radios, with a full incident management plan in place to deal with any incidents or accidents. Participants are led from start to finish by the qualified leaders.

    We are proud to partner with Charity Challenge whose safety record is exceptional and we are working with them to ensure that everything possible is maintained to continue providing this safe and positive experience on all our Defeat the Peak challenges.

  • What safety measures are in place?

    This is a leader-led challenge, and you will accompanied by our challenge mountain leaders at all times. Charity Challenge keep to a 1 leader for every 10 to 15 participant ratio, so it is crucial to listen to your mountain leader throughout your challenge.

    Charity Challenge employ experienced and fully qualified mountain leaders to accompany and lead you. The mountain leaders are first aid qualified and have extensive experience in leading expeditions throughout Britain and overseas. They will be ultimately responsible for the running of the itinerary and the safety of your group. They will be always carrying full safety equipment and mountain first aid kits with them. Your leading team are trained to deal with emergency situations in remote areas and will be carrying mobile phones and radios in case the emergency services need to be contacted.

  • Will I see the sunrise?
    These are designed as ‘Night’ challenges so it is not guaranteed that you will see the sunrise. It all depends on the group walking speed, the time of year and nature’s influences!
  • Will I reach the summit?
    In every circumstance we will aim for you to have the opportunity to reach the summit, but this all depends on the weather and group safety. If your group exceeds the time assigned to complete the challenge (8 hours plus), mountain leaders may encourage the group to turn back to ensure your group can return safely.
  • What should I wear for this challenge?

    For this challenge, we highly recommend getting a good pair of walking boots to break in ahead of your event. These events may take place over summer, but there can be a chill in the night so layer up and have a good waterproof to protect you from some inevitable rainfall. You also require a headtorch for this challenge, which Charity Challenge provide information on how to buy or hire.

    More details can be found in the Charity Challenge website.

  • What age can I be to take on this challenge?

    You can take on this challenge from age 14 and above, although all participants aged 14 to 17 will have to always have a parent or guardian with them during the challenge.

  • How much do I have to fundraise?
