The entire circuit, in particular its initial section, is quite fast with no really difficult or technical stretches. The routes along the valley bottoms run gently along farm tracks and quiet little roads. Fortunately, the ascents through forested areas - some of them long - are shaded and lead up to the alpine pastures of each slope. The balcony paths you then use (especially on the very beautiful second stage), run along or drop down via technical and fun singles treks. The day is spent well, with mind and body tested! The beautiful panoramic stopping points encountered all along the physical stretches will be welcomed as an opportunity to eat, contemplate... or have a siesta!
