Endeavour: Everest 1. By Canoe

In 1976 a British expedition made mountaineering history, becoming the first kayakers to descend the Dudh Kosi river that runs off Mount Everest. High in the Himalayas, and at incredible speed, six Olympicclass canoeists battled with white water over rocks, waterfalls and treacherous whirlpools. As they struggled to negotiate a 30pound canoe over a river with 30mph waterfalls, the threat of capsizing was ever present.
