Ah cool. Thanks. Looks pretty similar to the one the route planner threw up for me, but mine avoids the hill out of Dieppe (or into Dieppe in your case) and takes me along the disused railway line for a while before cutting south on the D-roads. I'll have a closer look at yours later and weigh it up. I might fancy the challenge of that Dieppe hill when I need to warm up at 5am when the ferry pulls in.
Just spotted this, sorry for the delay. The Rouen-Dieppe route is here
It's excellent. Winding roads through small villages, and even some hills!
