The route, along the former narrow-gauge railway line, connects Kalbe/Milde with Bismark and Hohenwulsch station. It's about 15 kilometers of freshly paved concrete, with occasional rest stops, and apart from other cyclists, the odd animal along the side of the path.
Somewhat confusing is the "Yield" sign, which gives way to intersecting field paths and farm access roads. I doubt this complies with German road traffic regulations, but on the other hand, I think agricultural vehicles and cyclists will easily be able to work out the way, as long as they're careful.
