The Yorkshire 3 Peaks Challenge is without a doubt one of the most rewarding challenges in the UK. Starting and ending in Horton-in-Ribblesdale you take in 3 of the best known peaks in Yorkshire; Pen-y-Ghent (694m), Whernside (736m) and Ingleborough (723m). The aim of the challenge is to walk this 24 mile route within 12 hours!
