Sorry for the delay, but I've finally got around to going over the gpx files.
Bear in mind they don't account of any possible excursions such as above, and are based on whatever the new version of Google maps thought Simon had in mind, so hopefully they line up ok.
Day 1 Brix to Bayeux - 65 miles, 2,200 ft. of climbing, quite flat really.
Day 2 Bayeux to Honfleur - 59 miles, 2,350 ft. of climbing, couple of big hills
(one of which is a tad steep, so don't blame me but it's got a nice view at the top).
Day 3 Honfleur to Dieppe - 70 miles, 3,257 ft. of climbing, bit of a drag up to a plateau, but nothing steeper than 7.8%, and I can see a lovely descent like Slugwash Lane, only longer with a thatched cottage thrown in.
You'll love it.
