If it's any consolation, I cycled around the Aquitaine Coast this summer and it's great. But even better, it will still be there for whenever you're ready to take it on. When you get there, stop off in Montelivet. IT's a great little town on the coast made up mainly of grids of little beach houses. They've got a main strip with cafes, shops and bars. Get there in the morning, and they have a great street market which includes some excellent oyster bars. It's got a real cosmopolitan feel. Hourtin, just down the coast is also a great stop off.
You'll love it.
