Flat ride along the Trebbia

The ride

From Gragnano Trebbiense you roll out past Castelbosco castle, then follow the Po river to the Regional Fluvial Park of the Trebbia. The Trebbia river guides you onward, with 57.9 km of riding that mixes paved and unpaved surface and only 155 m of climbing. Back to the start village, it's a route that keeps the legs turning without much fuss.
