Yorkshire Three Peaks

Twenty-four miles, roughly 1,600 metres of ascent, and a twelve-hour cut-off if you want it to count. Pen-y-ghent first, then Whernside past the Ribblehead Viaduct, then Ingleborough with tired legs.

Thousands do it every year and most of them remember the day precisely. All three prints together make an obvious set, and an obvious present for somebody who has just finished.
