Roll out of Alphen and let the route unfold: past the windmill Molenromp Zandeind, along De Buykse kuil lake, and through the Chaamse Bossen nature reserve before the road turns home. Of the 59.7 km, just over half runs unpaved, and the elevation gain stays at 41 m. It's a loop that mixes paved stretches with unpaved ones, from village streets to the woods and back.
