I always say I'm going to do it, next year, which one are you thinking of doing?
De Ingles is the shortest but the Del Norte looks like fun because you can get the ferry from England to the starting point (a bit like days of yore I suppose) if I did the Del Norte I'd want to cut off in the middle and follow the De Primitevo.
I hope you go, if you do be sure to tell us how you got on.
