I was after some advice, a group of us are going to cycle to Poland during the 2012 European football cahmapionships next year. We were going to cycle down to dublin, boat to Wales, down to bristol, London, Harwich, Netherlands, Germany(Frankfurt), Czech Rep (prague) and then up to Warsaw, Poland. We were just going to use the eurovelo for most of the trip, but I was wondering would we be able to do it on road bikes or would we need hybrids?? Has anyone got any experience of these routes? I'm particularly worried about Wales?
