Around 500 miles / 800Km from St Jean Pied de Port in France to Santiago de Compostela.  It took 27 days. Experienced pilgrims say that the first third of the journey is for the body; you toughen up, your legs stop cramping and you get into the rhythm of walking. The second third of the way is for the mind; you walk through the rolling Meseta landscape and your mind calms down. The last third is for the soul as you approach the ancient cathedral of Santiago.
