Pretty building at Bordes which forms the entrance to the castle.

Great stretch on the bus lane, about 2km long. Ideal because there's almost no motorized traffic. Perfect for pumping the pedals and picking up speed. If you have the wind at your back as a bonus, then you feel like you're growing wings.
