Different Routes to Le Mans

[Geo22]

Hi All, this will be my 4th Le Mans and we've always just stuck to the motorways when traveling from Calais. This year we are getting an earlier ferry so we have more time to take the scenic route, any suggestions on some alternative routes to take hopefully including somewhere good to stop for a nice lunch!

Doesn't have to be all avoiding motorways just fancy a change this year.
