Good call. I seriously need to do this, but it will be LWL first. I just don't know if I can do it, I suppose you just have to go for it. One year I plan to do just that, not sure if it'll be 2018 though...
You could do worse than head up through Nyons to Vercors & the Diois region. When are you thinking about going?
Ah, I won't be in residence till the 20-somethingth of July. But the whole area east of the Rhône between CNDP & roughly Valence is worth exploring. Depends how many days you want to spend touring, and how far you want to do a day. I'd comfortably get from CNDP to Die in a day, then you could head over Vercors towards Grenoble, head back south through the Trièves area down to Serres, and thence back to CNDP. You could even head a bit further east if you wanted to do some of Dévoluy - col de Noyer is worth the effort, if you like hills.
Hmm, OK. Do you both like hills? Once I know that, I'll sketch out a possible route, which you are welcome to ignore!
We did 2 weeks around Brittany this year. While they weren't massive there were lots of them!
Well, the hills (well, some people might call them mountains) round my area are long and pretty gentle (6-8% typically, 10% would count as steep), whereas in Brittany it's probably a bit more like Cornwall, sharp ups & downs the whole time.
