September 27, 2025,Dammgraben-Runde von Clausthal-Zellerfeld

This time it was wet and muddy, which increased the technical challenge a bit. It was great, it was fun.

As sad as it looks in the Harz Mountains, the tour was absolutely great 👍.
There was a bit of everything, including wet feet 😂

Well either Komoot changed something myself or I planned it myself ... and Dammgrabentrail has nothing special today due to the mostly completely missing trees 🤷🏼‍♂️

April 8, 2025,Der Dammgraben🛶- längster Trail Deutschlands!?

Today we cycled along what is supposedly Germany's longest trail—the Dammgraben in the Harz Mountains!

The trail is very rooty at the beginning, but later becomes nicely flowing!

Some sections seem to be avoided even by hikers🤷🏻. It'll certainly be difficult to cycle there in summer🚫.

This time everything was there .. Mud, roots (lots of roots) water crossings, nice fast single trails and finally a crisp increase
