Fell running - Wikipedia
Fell running, also sometimes known as hill running, but not to be confused with mountain running, is the sport of running and racing, off road, over upland country where the gradient climbed is a significant component of the difficulty. The name arises from the origins of the English sport on the fells of northern Britain, especially those in the Lake District. It has elements of trail running, cross country and mountain running, but is also distinct from those disciplines.
