Thanks for the tips everyone! @ough really appreciate the sound sense. I think we'd maybe be able to haggle a lift with a friend to Plymouth so that could be quite simple.
Another option would be to just drive ourselves down to Nantes from the ferry and leave our car there. Removes the risk element at least I suppose, and might mean we can just relax a bit more

Once in Nantes it looks like we could probably take the Velo loire trains pretty easily - https://en.francevelotourisme.com/tips-and-advices/getting-to-and-around-france-with-a-bicycle/train-velo-loire
