Riding from Liverpool to Leeds along the canal seems to be increasingly popular. Most recently Adam Hope and the Burnley Boys have ridden from Liverpool to Burnley and then Leeds over two days.
Here is their account of the ride:

They weren't very lucky with the weather or punctures but if the photos are anything to go by they enjoyed themselves. They got in the local papers too: http://www.lancashiretelegraph.co.uk/sport/9242428.Burnley_cricketers_raise_over___3_000_from_canalside_trek/
Just as impressive as the ride itself is the money they raised for cancer charities, if you feel like it why not chuck them a few quid here: http://www.justgiving.com/teams/burnleyboys

Well done to everyone who has done the ride!
