Looks great, Richard! Enjoy it.
It looks very similar to my sherpa, Red, and you have the 853 fork, same as mine? Good low gears as well. The only real difference is that I have a Tubus rack.
I don't know any of the Welsh rides you refer to, but the Brittany / Normandy one would be good. There is a cycle route from Mont St Michel to Paris which I have done (as far as Chartres anyway) which takes you well into Normandy, with I think a loop up to Caen or the Cotentin peninsula. Lovely riding.
