C’est le champion du Monde du contre la montre, Filippo Ganna (Ineos Grenadiers) qui a remporté la 1ère étape, un contre la montre de 8,6 kilomètres, dans les rues de Turin.
Avec un temps canon en 8 minutes et 47 secondes, soit une moyenne de 58, 748 km/h, l’Italien devance de presque 10 secondes Edoardo Affini et Tobias Foss (tous deux Jumbo Visma).
Le Français Rémi Cavagan prend une belle 5ème place à 17 secondes de l’Italien, et Remco Evenpoel signe une 7ème place à 19 secondes pour sa reprise en compétition.
Ganna endosse, bien sûr, le maillot Rose de leader du général
