Dunno if this is really the right place for it, but the guys who came up with a journey planner for the Cambridge Cycle Campaign have developed the idea to nationwide, and the site is now in open Beta, here. It works pretty well- though if you do have problems, please, please contact the developers with them- you'll help them make it better.
it has journey options for "Fastest", "Shortest" and "Quietest"- the latter will try to use side roads, off-road cyle paths etc at the expense of a perhaps more winding route.
