This year, a team of dedicated walkers From DSD has decided to tackle the Yorkshire Three Peaks challenge to raise funds for Cure Leukaemia.
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.
