MERIBEL, France (Reuters) - Primoz Roglic took a giant leap towards a maiden Tour de France title when he extended his overall lead after the 17th stage on Wednesday, an unforgiving mountain rollercoaster dominated by Colombian Miguel Angel Lopez.

Lopez prevailed at the end of the 170-km trek from Grenoble, 15 seconds ahead of Roglic, who extended his advantage over fellow Slovenian Tadej Pogacar to 57 seconds, four days before the final parade in Paris.
