I ran out and back, starting in Bielefeld-Schildesche. The faster leg was the 2nd leg, from North to South.
The route is very well runnable with rolling hills. There are a few very beautiful typical farm houses along the way.
For the amount of rain over the last days there were only little stretches with deep mud. The only not so nice part is the stretch running up to the town of Enger, which is a main road without a bike path.
The route is well marked with “Hp” as mentioned in the description. My Garmin measured somewhat twice as much vertical gain as compared to the route description.
