My favourite all time run is that way Al. A friend was doing the langdale marathon so they were out for i think 5 hours. I headed from The dungeon ghyll pub. Straight up the path at the back to loft crag and then because of the clag back down to a waterfall crossed over and got harrison stickle in as well. Its about 7 miles with 3000ft and can be done in 1:30ish with a few camera stops. Definately recommend it
