Good luck with that !
Its something I was going to organise for our crew a couple of years ago, in theory it shouldn't be too bad, canals don't go uphills (much) and there is a path alongside them (sometimes).
Then I remembered the section that I've ridden in the past beyond Skipton up towards Slaidburn and how we eventually gave it up and rode on the roads instead because we were on road touring bikes and they were getting hammered to hell and back on what was jokingly called a towpath but was actually a narrow stony track that threw you off the bike every twenty yards.
Don't want to put you off or anything
