The Yorkshire Three Peaks route is 24 miles (38.6km), and includes 1585m (5200ft) of ascent. The Yorkshire Three Peaks Challenge takes on the peaks of Pen-y-ghent, Whernside and Ingleborough, usually in this order, and in under 12 hours. These peaks form part of the Pennine range, and encircle the head of the valley of the River Ribble, in the Yorkshire Dales National Park.
