One of the best of the new generation of young climbers, Leo Houlding, teams up with one of the greatest legends in mountaineering, Sir Chris Bonington to celebrate his 70th birthday. They travel out to Australia to the fabulous Blue Mountains near Sydney.
Leo says: 'Chris is one of my heroes and my inspiration. I've got to know him pretty well in the last few years, but until now we have never climbed together. It doesn't matter that he's almost 70 and I'm 23. I'm really looking forward to climbing with him.'
Over three climbs the protégé learns more about his hero.
Sir Chris says: 'I've got a deep, passionate love for the mountains. I love the Lake District. That's the core that keeps me going.'
As young and old start their first climb, Sir Chris tells Leo about his life and how he got into climbing. He says: 'My Dad walked out after nine months and it was my grandmother who brought me up while my mum went out working. I always had a terrific void of not having a father and other kids did.'
He was introduced to climbing at 16 by his German grandfather in Ireland and has never stopped since. 'I climb for pleasure, not for challenges,' says Sir Chris. 'And then various challenges have crept into it. Whether all of those things are compensation for my disturbed upbringing, I just don't know.'
Sir Chris says the support of his wife of 42 years, Wendy, has been crucial to his climbing career. He worked as a margarine salesman when they met in 1962 and it was his newly-wed wife who encouraged him to leave his job and take a career in mountaineering.
Sir Chris became famous with the successful 1975 expedition to the world's highest mountain, Everest, but it was not until 1985 that he himself reached the top. 'I did not realise how important it was for me to get to the top of Everest. I was 50. It was important emotionally,' says Sir Chris.
Leo was only five when Sir Chris reached the summit of Everest!
Sir Chris says: 'I first became aware of Leo when he was 12 or 13 and climbing various road-side crags in the Lake District. He's one of the most brilliant young climbers who I have seen in a long time. The concern is that he's climbing at the absolute edge the whole time and he's addicted to risk.'
