My colleagues and I are going to be climbing the Yorkshire 3 peaks in a fortnights time. This challenge is going to be tougher as we will be scaling Pen-y-Ghent (691 metres), Whernside (728 metres) and Ingleborough (723 metres). We will be doing this for the Great Ormond Street Hospital who do so much great work, so a little hard work from us will help them to do theirs!
