The National Three Peaks Challenge is an event in which participants attempt to climb the highest mountains of England, Scotland and Wales within 24 hours. Walkers climb each peak in turn, and are driven from the foot of one mountain to the next.

The total walking distance is 23 miles (37km) and the total ascent is 3064 metres (10,052ft) - twice the ascent of the Yorkshire Three Peaks, over a similar total walking distance. The total driving distance is 462 miles.
