As mentioned, there are some great discussions of route choices at:

http://forum.fellrunner.org.uk/showt...-Route-Choices

However, that thread is from 2007. Is it worth revisiting some of those options? In particular I'm thinking of Great Calva to Blencathra which alwalysinjured and bob discuss around post #104. The options differ partly due to the length of the heather and the visibility of trods, which may well have changed in the last 7 years. Anyone got any up to date info / opinions?
