Roll out of Grethem and let the ride unfold: first the Holtorfer Moor nature reserve, then the Steimbker Kuhlen nature reserve, and on past the Weißer Graben nature reserve. The route runs 77.3 km and is entirely paved, with 157 m of elevation gain along the way. The Aller river accompanies you before the road turns back toward Grethem. Quiet miles, easy climbing, and a finish where you started.
