UAE Team Emirates - XRG's Slovenian rider Tadej Pogacar celebrates on the podium with the best climber's polka dot (dotted) jersey after the 14th stage of the 113th edition of the Tour de France.

Tadej Pogacar won an "unforgettable" mountainous 14th stage of the Tour de France amidst huge crowds in the Vosges on Saturday to extend his lead over Jonas Vingegaard to four and a half minutes.

It was the world champion's fourth stage win in this 113th edition of the Grande Boucle as his team-mate Isaac Del Toro pipped teenager Paul Seixas to second place, with Vingegaard fourth at the end of the 155km stage from Mulhouse to Le Markstein Fellering.

"I must say thanks to all the fans that came to the side of the road, it was really something unforgettable," the 27-year-old Slovenian said.

"To see all the crowds on the hills, over the mountain... I (have) never seen something like this.
