Currently touring in France and asking for help with route

So I am almost 2 weeks into my France tour and having a blast. I started in Paris (flew from my home of Australia), and am currently in Nantes. The highlight so far has been the Normandy beaches and D-Day sites which I found to be very emotional. The lowlight has been the wet weather, but I cant control that so don’t let it get to me (Note to French people – telling me how nice the weather was in April really doesn’t help!).

You can see on the first pic where I have been so far and I will now head east along the Loire Valley before heading south.

What I am please asking for is help with is guidance on the best way from the Loire Valley to the Pyrenees, where I want to tackle some of the TDF climbs like Col du Tourmalet etc etc

There just seem to be so many options that I am quite unsure. I have come with the rough route on the second and third images from a few sources. I will probably change and work out details on the fly as I usually do, but do these look like good areas to be heading through?

What I am ideally looking for

– Great scenery, nice interesting villages and getting off the beaten track. The Dordogne region seems to meet this requirement

– Don’t want to follow the coast

– I am not really that interested in EV routes. I understand their attraction, but my experience so far on this trip and others has been that meandering along bike paths and green corridors gets boring very quickly. I tried parts of the EV routes, but have ended up riding on the roads instead in many cases. I have preferred this as there seems to be better scenery and you also get to go through all the villages and see cool stuff that the EV routes seems to bypass. I have also found French drivers to be very patient and considerate of cyclists so have no issue with riding on roads (compared to the psychos in my home country Australia )

– I don’t mind hills, in fact refer undulating to flat.

– I’ve been staying in municipal campsites where possible, which have been awesome. At a couple I have been the only person staying which has been great as I have been able to pitch undercover, I guess a benefit of the early time of year and bad weather.

Thank you for any input
