Hey i am interested in riding along the coast next spring. I might want to start in Paris, go to Brest, France and then south untill Lisbon, and along the coast to Barcelona and beyond. I plan to camp on the beach and to stay in hostels when i reach big cities. I havent yet decided if i should do this on a bike or maybe on roller skis? I dont know much about the latter. But i thought 1 advantage would be that if i become bored it's always easy to catch a train or a bus, even for short 50km trips. While taking a bicycle on a train is really problemmatic. But one disadvantage of rollerskis are the boots. Ski boots become very sweaty when it's >0 and they are not waterproof, so i might be in real trouble when it rains.

So please assume that i'll go on a bike. I'm looking here for anybody else who might be interested to make company. I dont have set dates but I intend to go to europe for at least 2months starting in either March or April. And if i go alone, im looking for some tips!

Does it rain a lot in normandy, coastal spain, etc in spring? is the whole coastal area of europe covered with sandy beaches where i can sleep every night without any problems? and if it's a blue flag beach, i can even take a shower?
thanks!
