Episode 2

Having reached the South Pole and the highest summits of Antarctica, South America and Africa, Richard Parks's next destination on his 737 Challenge was Carstensz Pyramid in Indonesia. A difficult technical climb compounded by a 100 kilometre trek through the jungle - and Richard's knees were showing serious signs of wear and tear. His medical team were afraid that the whole project was in jeopardy.

The relentless nature of this adventure would then see him join forces with Olympic Gold medallist Steve Williams to reach the North Pole and then to attempt Everest. Jungles, injections, ice plains and savage environments - all part and parcel of his attempt to set a world record and raise funds for a cancer charity.
