Suspect taylforth was taking the piss again.
Have been thinking about this for a while but never worked out a route fully. Could start ambleside and head over the bridleway to stonethwaite (bottom of borrrowdale) Then over Styhead to Wasdale head (Could also go over the Honister and via Ennerdale and Blacksail sp?? to Wasdale. Overnight stop.
From wasdale you could take the bridleway over to Eskdale (I have never done it so could be a mare) then take the bridalway from the bottom of the hardnott over to duddondale and then over the walna scar and back to ambleside. Would be 2 very long days. Would need to have a look at a map to really work out how long it would all take.
