Langs La Somme en La Somme Canalisée

The ride

Roll out of Rosières-en-Santerre and let the ride unfold, with most of the 63.1 km running unpaved. You pass the canal La Somme Canalisée, then follow the river La Somme before looping back to the village. It's a flat-ish day with 287 m of climbing spread along the way.
