Canadian Woods finished 10 seconds adrift of Hamilton in Cascia on a stage that featured the highest point of the race -- 1,521 meters at Rifugio Perugia.

Woods, who rides for the EF Pro Cycling team, was at the front of a group including overall favorites Geraint Thomas, Rafal Majka, and Simon Yates.

Jakob Fuglsang and Vincenzo Nibali, like Thomas another former Tour de France winner, both lost over a minute after failing to keep up on the 194km route from Terni.

Four-time Tour de France champion Chris Froome crossed the line almost 10 minutes off the pace, underlining the concerns over his form which prompted Ineos to leave him off their team for the Grande Boucle.
