I am starting to think about possible tours for next year and one of the options I am considering is to fly out to Biarritz and cycle home mainly along EuroVelo 1 (La Velodyssee). Does anyone have any experience of this route? What are the surfaces like? Is the southern end interesting or just flat and foresty?
If you can stand the early climbing there is a ferry service from Portsmouth to Bilbao. Hard work from there to the border but then it's OK.
