I've done the following a couple of times and liked it:
Ride from London to Portsmouth (65 miles form S.London)
Get on night ferry to le Havre and have a good night sleep!
Cycle approximately along Seine Valley up to Paris....highlights: Rouen town centre, Les Andelys (nice descent) and you go right past Monet's House and garden
(bridge over lilies) at Giverny.
You're either cycling on a plateau or in the valley so apart from the couple of times you switch from one to the other, it's pretty flat....about 150 miles in France as I can remember, but might be wrong....
