France and beyond in September

I am hoping to do a cycle tour starting by taking the eurotunnel from Folkestone to Calais and then heading off through Europe. I haven't got a concrete route yet, however I hope to travel through France, then onto Italy or Spain, or potentially through Italy and into Eastern Europe and beyond!! I have no exact plan yet, however I would be using Warmshowers and camping and it would be a low budget trip. I would hope to do fairly long mornings and afternoon rides from 60-160km depending on the mood/scenery and roads. If I end up going solo it may be a short trip, however I am leaving open the possibility that I find someone to go with and we turn it into a longer adventure! I am 25, recently left my job as an environmental consultant, I have many interests from discussing politics and philosophy (badly) to Brazilian music, football, all sports and yoga/meditation. I usually get on with most people and enjoy spending time with people exactly like me or completely the opposite to me so whoever you are, if you fancy meeting up for a little or a lot of the cycle let me know.
