On Friday 20th September Team Pudsey is taking on the Yorkshire Three Peaks Challenge, hiking the peaks of Pen-y-Ghent (694 metres), Whernside (736 metres) and Ingleborough (723 metres), in under 12 hours. Every step of this challenge is making a difference to the lives of children across the UK. BBC Children in Need believes that every child should have the chance to thrive and be the best they can be.
