Twelve days, with three doubled-up stages: Ortu di u Piobbu – Haut-Asco (12 km, 1,400 m of ascent), with a lunch stop at Carrozzu; Manganu – Onda via Petra Piana; and Onda – E Capannelle (24 km), passing through Vizzavona in the middle of the day. The south then follows the official pace, with the direct crossing from Usciolu to Asinau.
This itinerary is aimed at trained walkers who can string together days of 8 to 10 hours on technical terrain. The long Ciottulu di i Mori – Manganu stage (25 km) is still done in one go.
