We are thinking of riding 400 km, then see sites in area two more days, repeat two more times.
Or, ride 2 - 400 km day, taking in sites, different each day after.
Or something in between.
We have four days before this in A Caruna, then we take train to Madrid. Our thought is likely ensure we take in Andalucia area. Art, Culture (including local sports, as this defines local culture), Scenery, and even Horses are the goal. No bumper to bumper four lanes.
