Jonas Vingegaard held the 10-second overall lead in the Tour de France, and Dutch veteran Wout Poels single-handedly triumphed on the mountaintop after a tough climb in the Alps.
Part of an early breakup on stage 15 on Sunday, Poels took advantage of a short but very steep slope just before the final 7km climb to the finish line.
Wout van Aert finished second on the stage podium of Mathieu Burgaudeau, more than two minutes behind.
Vingegaard and two-time Tour winner Tadej Pogacar, who have been fighting for the yellow jersey since the start of the race, stayed together again in the main competitors group throughout the day.
Pogacar tried to get away from his opponent 900 meters from the line, but reigning champion Vingegaard quickly got behind the wheel and wasted no time. Their duel will continue in Tuesday’s time trial.
Monday is rest day.
