In the second week of the Tour, he won stage 9 to Loudenvielle by out sprinting rivals Primož Roglič and Egan Bernal, as well as Marc Hirschi, who had been on an 80 kilometer solo breakaway, on the line. In the third week, he won stage 15, which was another mountain stage that finished at the summit of the Col du Grand Colombier. At this point, Pogačar found himself in 2nd place overall, within a minute of his countryman Primož Roglič, who was in the lead at that point. On the penultimate stage of the Tour, which was a 36-kilometer time trial featuring La Planche des Belles Filles, he won his third stage of the Tour. In a historic individual performance, he finished ahead of Tom Dumoulin and Richie Porte by 1'21. More importantly, he defeated his countryman Roglič by 1'56, taking over the lead of the general classification with an advantage of 59 seconds going into the final stage to Paris. In addition to putting himself in position to win the Tour, he also solidified his grip on the young rider classification with a nearly six-minute advantage on the next closest rider, Enric Mas. By achieving the fastest time up the climb of La Planche des Belles Filles, Pogačar also took the lead in the mountains classification. He is one of 7 men to win the Tour de France on their first attempt, the previous being Laurent Fignon in 1983.
