Did the full length route out of some bike mag. 18 miles on the Friday taking in all the hills and then did the reverse route the next day. 18 miles doesn't sound much but I have to say it was pretty hard going in places. The toughest hill we came across was on Saturday while doing a variation of Friday's route, straight up Hangman's Hill / Broad down from Shadeybank common on the return leg. Had me blowing a bit!
