Hello again Jeanine. I can see you have walked the Camino before. Great!
I am not sure if you have been to France to walk before. If so I don't want to put you off in any way
. I loved it and all things being equal would go back again tomorrow..
But just be aware, and I hope others might agree I am not exaggerating. The northernmost part of the VF through France goes through areas of very sparse population. It makes the small villages of the CF look quite cosmopolitan. And of course there are wonderful cities along the way too. But the reality is you may sometimes walk for two or even three days without seeing a shop. You can work around this and you can get used to it! When you do see a shop, stock up on foodstuffs. You will never walk past one without going in!
Old villages are dying. The church is closed and ALL the shops - butcher, baker, grocer and bar - are closed. This is reality. I talk a lot with local people as I walk as I nearly always walk alone. Many people rely on a mobile shop coming once a week. You will bump into it occasionally. You will pass through enormous fields, wheat and potatoes I would say mostly. Two or three young men can farm many many hundreds of acres with a modern GPX tractor. You don't see smallholdings any more.
Sometimes in a village you will see a vending machine with a few baguettes, a little cheese and a few eggs. I never bought them as I always imagined I would be depriving a local inhabitant of what they were relying on. Occasionally you may see someone selling eggs or cheese or vegetables at a farm gate but this is rare.
This is part of the reason you must let your host know that you are coming. They cannot hop down to the corner shop to get stuff for your supper.
Having said this there are great networks of home stays and people who are very sympathetic to pilgrims. Especially the pilgrim office in Chalons-en-Champagne (in Notre Dame church, not the cathedral) and the volunteers in the Cathedral in Reims will help you. Both of these are crossover points with Camino routes.
It is perfectly manageable. You will need a bit of ingenuity at times!
I never failed to find accommodatio of some sort.
