Roll out from Parkeerplaats Loonse en Drunense Duinen and straight into the nature reserve of the same name. Then it's castle to castle: Het Witte Kasteel, Kasteel Nederhemert and Kasteel Ammersoyen, with the windmill De Witte Molen and nature reserve Langstraat in between. The Oude Dieze and Dieze rivers carry you along the final stretch. Just over 73 km, mostly paved with a chunk of unpaved, and barely any climbing.
