With great respect - I never understand why people do this, i.e. down one side and back the other when there are so many fantastic passes over the Pyrenees one can just hop over an back again, often three or four times in the same day.
Hi Simon,
I didn't explain my plan particularly well and when I said the French side what I really meant was when we head back, East to West, we have 3 and half days to explore on the way back to Santander. On the way out, West to East we have to get from Yesa to Cellers on day 1 before riding to Reus to meet our families for a week in Portadventura. When they leave for the airport we start back to Santander. So when I said French side what I meant, like you advised was to affectively zig zag back but being able to explore more towards France side than we can on way out.
