No worries mate, you may have missed on the map last night the arrows I put on the routes.
The green route is for going to Amiens taking a nice scenic coast/somme valley road.
The red one is the one you originally put (with a slight mod toward the end to follow the river) and is quicker.
I think peeps will prefer the slower scenic route in the morning and will also prefer a quicker journey back to the hotel. This may have to be reversed though, depending on the timing we can agree with the hortillonnages
