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 Olympic-class canoeists battled with white water over rocks, waterfalls and treacherous whirlpools. As they struggled to negotiate a 30-pound canoe over a river with 30mph waterfalls, the threat of capsizing was ever present.
