Toulouse-Preston... and Europe!

Time passing...thinking....,I start to see few routes shaping themselves in my mind.....
I reported years ago a cycling trip to Irland..,the turn of Irland..with a mate from Toulouse,I will surely enjoy my georaphical position once in Preston to go and cycle in Irland ,as I will be close to the heart of Europe too,I will go there...Benelux and Germany...passe throught my mind first..
I went there when I was young boy but not much of memories...so is for that I am going to see what's going on in this northern western europe..as I will be in the area.
