thanks for the info , what i read was stick to D or N roads ,unsure if that is correct ive only really just started reseaching , and there seamed to Be D or N roads all the way to Montpellier via GrenobleI know that area fairly well. Once you go ESE of Cluses towards Sallanches and Chamonix the roads are not particularly quiet, though I have ridden out that way. Chamonix is not really a road cycling destination as apart from the valley floor, the roads out of town are pretty fast, this is clearly visible on Google maps. I have ridden out to Sallanches to watch a mountain time trial for the TdF a few years back, which was ok, but the roads after Sallanches towards Chamonix are very unpleasant.
