The mileage each day turns out to be quite a bit more than it is supposed to be, the answer to this is simple, I make stupid mistakes. Yesterday I overshot the hotel by failing to realise that it was not in the town itself but in a beach resort on the other side of a river. So I had to turn back and re - cross the bridge which gave me the willies the first time. An extra 2 miles. This morning I figured I had walked that bit, albeit in the wrong direction, so took a cab to where I did a u turn.
Portugese towns give a whole new meaning to the word 'sprawling'. I walked for well over an hour before getting through the town and it's beach front where the Camino turned inland.
