It's not called the 'Marathon with Mountains' for nothing. Enter the Three Peaks Race and you face a 23-mile slog over the mountains of Penyghent, Whernside and Ingleborough in the Yorkshire Dales.
The 2018 race will be the 64th. It was first run in 1954 from the Hill Inn at Chapel-Le-Dale when there were six starters and three finishers. Today, it is renowned in the international fell running calendar.
