bike the camino de santiago

I have no idea when I will do this. I’m not very good at planning (I usually book my trips right before I go) and to do this you better prepare a lot first. All I know so far is that I’d like to start from Saint Jean Pied de Port and that I’d like to go either in March-May or September-November when it’s not too warm and not too crowdy.

The camino de santiago is an ancient pilgrim’s route to the santiago de compostela cathedral, where the apostle james is buried. Modern day pilgrims walk, bike or horse ride this route through spain, often staying at very modest pilgim shelters and sharing this experience with many travellers.
I would like to take the “french route” on bike from roncesvalles in the french pyrenees, through aragón, navarra, la rioja, castilla ann león to galicia, about 769 km.
