Geraint Thomas slipped further behind the defending Tour de France champion, Tadej Pogacar, as Bob Jungels, riding for the AG2R Citroën team, took his first career stage win after a 50km attack through the climbs of the Swiss Valais and Haute Savoie.
After a day in the mountains, Thomas marked Pogacar, leader of UAE Team Emirates, closely until the final few moments of the stage, when the Slovenian slipped clear with his closest rival Jonas Vingegaard to steal just three seconds on the other contenders.
