Seven days for the northern half, combining two pairs of stages: Ortu di u Piobbu – Haut-Asco via Carrozzu, and Petra Piana – Vizzavona via the Onda hut. The night at Castel di Vergio splits the long Golo stage. Days average 13 km with 1,000 m of ascent.
It is a common format for a one-week holiday: fly into Calvi and spend the night before in Calenzana, then head home by train from Vizzavona.
