Cheers Andy - I appreciate that . I'll take a good look at your route. We're planning on catching the 5:30pm ferry after reaching Newhaven. The first one the next day won't get us into Dieppe until 2pm so need to get the 5:30 one. I'm assuming an average of 12mph which will help dictate the start point/time in London. Two of us will be cycling Chester to London over two days beforehand, so the slower pace to Paris will be welcome The French side of the route I'm planning looks really quite nice with plenty of off-road cycle paths (mainly along the Avenue Verte) and enters Paris from the West along wooded paths.
