Roll out of Glinde and let the ride unfold: first past the Braaker Mühle windmill, then on to the Hoisdorfer Teiche nature reserve. The route keeps going through the Mühlenbachtal bei Trittau and the Hahnheide, both nature reserves, before the Billetal nature reserve rounds things off. With 73.2 km and 320 m of climbing, it's all paved — no unpaved sections at all. And then you're back in Glinde.
