Due to the extreme weather conditions, the organization cancelled the Italian section of the 13th stage.

The 13th stage of the “pink race” passes through the Aosta Valley region: departure from Borgofranco d’Ivrea and arrival in Crans-Montana.

The stage involved the passage from the Great Saint Bernard mountain pass which would have been the Cima Coppi of the 2023 edition, the highest point, in terms of altitude, reached by cyclists during the Giro.
However, the adverse weather conditions, led the organizers to modify the last section of the route.

From Pont-Saint-Martin the stage proceeds towards Bard, at the foot of the famous fortress, and then again along the central valley touching Saint-Vincent, Châtillon, Nus to arrive at Aosta, the chief-town of the region. From here the route climbs along the Great Saint Bernard valley. Then the caravan will pass through the Great Saint Bernard tunnel into Switzerland without reaching the historical pass.
