We have been looking into several possibilities, however. One option would be to walk the entire Camino Frances from Saint Jean Pied de Port to Muxia in one inning, as some of our friends and former students have done. That would be a worthy challenge, but has some downsides, including the likely wear and tear on our bodies, and the fact that we would be covering old ground, some of which we have already covered three times. So we're considering the Camino Portugues, parts of the Chemin de Arles, and the Via Francigena (the Florence to Rome section).
Any advice or recommendations will be welcome.
