I decided to stop the night outside the Chateau Villandry, which I intend to visit in the morning. The hotel next door were doing a too-good-to-be-true menu of the day. As it turned out, it was just good and true, and once more my faith in French cuisine is restored after several years of less them impressive meals.
Might need to fit some cycling in tomorrow before the rain arrives, but them I have some vineyards and up to three Chateaux on the itinerary, so I may be running some of it!
