Polar explorer Mark Wood has lead and trained people in cold weather survival for major Polar expeditions including the BBC Top Gear team on their race to the Magnetic North Poles. He also runs dog sledging teams in Alaska and supports local schools in Nepal who live in the shadow of Everest.

The Mount Everest expedition caters for groups or individuals with all different types of strengths and goals. It will help to fund the education of children in the villages you trek through.
