Roscoff to Le Clôitre St Thégonnac. Deuxième désastre!

The road into Morlaix that we chose at Lanvéguen (D769) in preference to the signed cycle route was lovely- wide, smooth, lightly trafficked. We rolled into Morlaix, under the motorway viaduct and towards the double height railway viaduct feeling good.

Then disaster struck.

"TWANG!!".
