I would like some advise primarily; does anyone know if this has been done?
Regardless, i'm going to give it a go, and will do so for charity.
My plan would be to head from the UK to Holland via ferry, and then get to the border with Belgium to start. From there- head south- through 7 other countries. The proposed route, which I would happily share with any interested parties, is just shy of 800km.
