Julian Lines was filmed edging towards the top of the cliff - without any equipment to stop him plummeting into the freezing water below.

Don't look down: The solo climber clings to the side of the cliff - hugging his body to the stone - as he climbs further from the freezing water . While the ascent would leave most with their palms sweating, Mr Lines, from Northern Ireland, said 'life's problems evaporate' when he is climbing. But he admitted there had been times he had fallen and had 'really close calls'. He said: 'There's a lot of feeling and emotions going on when soloing. It's quite complex, yet so simple. 'Although you have to be clear headed before you start soloing, once you're up there life's problems just seem to evaporate. 'Of course there are fears and nerves, more so now that I'm older. In fact I don't really like it anymore if I'm more than about 60ft up . 'I don't worry about slipping, I worry about my arms tiring rapidly and not being able to hold on. It's all about speed and precision. 'Slipping is uncommon unless I'm really tired or the standard of the climb is of the upmost difficulty. Risks: Mr Lines said slipping is uncommon, but he worries about not being able to hold on if his arms tiring rapidly during an ascent . Fearful: Mr Lines said 'his inner mortality was catching up' with him, which makes climbing more difficult than it used to be .

Planning: The 42-year-old said solo climbing is about risk assessing, calculating and fine tuning in order to 'minimise the inevitable' 'In more than 25 years of soloing, I've had some really close calls. Soloing is all about risk assessing, calculating it all correctly and fine tuning to minimise the inevitable. 'There have been times when I've actually fallen and been so lucky with the way I've landed it's close to miraculous.' All of these stories are written in Julian's book 'Tears of the Dawn' which was published last year and won the prestigious Boardman Tasker award for mountain literature in 2014. Alastair Lee, director at Posing Productions, who recorded the footage said: 'Jules is very much the dark horse of British climbing and easily the most accomplished free soloist in the UK. 'Filming soloing isn't for the faint hearted but it was a spectacular journey we embarked on as Jules guided around many of his favourite climbing destinations.'
