In reply to Tom W:
There used to be a classic fell race called Black Combe, I don't know if it is still run but it's a good horseshoe and I seem to remember that was in South Lakes.
Memorable for me was the Dunnerdale Horeshoe, a 22 miler, mainly because I was first back into the village to great cheers, only to get outsprinted to the finish by the course record holder (who I was only in front of because he had somehow taken a wrong line of one of the checkpoints) This was my best ever finish, 2nd, in a Lakes fell race..
