The route submitted is a cracking route. I also like craigwend's joke routemaster route.
I'm not really convinced of the need to have it in Yorkshire though, as rich said London to Dover was just about stretching it and it was very nice having it the sections of tours abroad is getting ever more ridiculous. I think what'll probably happen is that you'll get various places desperate for the tourism and prestige - Leeds, York, Hull and Sheffield squabbling over it and not as much focus on the route or trying to promote cycling. Large parts of Yorkshire are after all cycling deserts.
