Climbing as One

Solidarity is essential in the fight against Covid-19

Mt. Kilimanjaro

Since 2006, Tim Challen has led over 650 climbers to the top of Mount Kilimanjaro (5895m), the highest freestanding mountain in the world, raising awareness and funds for various social issues.

The impact of The Big Climbs, whilst difficult to qualitatively calculate, can be summarised as follows:

  • Life changing experience for each climber, bringing together diverse individuals from around to planet with a common goal
  • Life changing experience for the selected youth, trained and supported to become community champions through educational, professional and leadership opportunities including scholarships
  • Supporting thousands of family members of the guides, porters and cooks involved in the climb. It is estimated that The Big Climb Mt. Kilimanjaro 2022, provided support for the 75 guides, cooks and porters and their families for 4 months. Estimated number of persons impacted = 450
  • Investment in renewable energy solutions for the local community including solar panels for the Marangu Hospital, Tanzania
  • Hundreds of trees planted around the Marangu community
  • Funds raised for Covid vaccines in 2021
  • Donations of clothing, educational material and goods to the local communities
  • In 2022, 16,500 USD was raised for the Red Rose Primary School in Kibera, Africa’s largest slum. 400 students attend the school, located in one of the poorest communities in Nairobi, Kenya
And contribution to the UN’s Sustainable Development Goals (SDGs)

“Mountains are the water towers of our civilizations. We must treat their environments with great respect, and support their fragile ways of life in the face of rapidly growing urbanization, tourism and consumerism”.
