Yes the aim is definatly for Ireland.. the thoughts were either of your route you suggested via bikely, or to stay on the other side of the pyrenese until we hit the coast, then head for Bordeaux. ie Passing Zaragoza and Pamlona...
Im not sure if its a great area to cycle, everyone talks of France as the place to be.... The real only reason we are thinking of stayin in Spain as long as possible is because we have spent a good few months learning the language...
Though your route looks fantastic, along the coast, through Toulouse...
Btw, every time you mention a route, probably that everyone knows, im googling it, ive never heard of most of these routes, embarressing as that is.. my geography/history isnt great.
