This long loop goes from the Loire watershed to the Rhône watershed, crossing the watershed twice. After a first part with lots of elevation changesuntil the Col du Pin Bouchain, the passage of the Turdine valley at the Joux dam offers a deserved rest, before a new effort to reach Notre-Dame de la Roche. The reward is the view on Tarare and a passage at the foot of the four windmills of Valsonne.

Between 3h20h to 4h40, depending on the pace.
