We did a nice tour from Roquefort, Biot, Sophia, Valbonne and then back to Roquefort. The only tough up was entering Sophia from Biot.
This live map shows the route. The only hard bit was from Biot to Green Sides in Sophia. I used GPS Visualizer to create the live map from my GPS data–very cool.
The Distance vs Elevation profile below shows a one up and one down with many small ups/downs. (click on it for full size image).
