Tadej Pogačar did not just win another mountain stage of the Tour de France on Thursday. He rewrote a piece of cycling history that had stood since before he was born, tearing up Alpe d'Huez's 21 hairpins in a time nobody had ever come close to.

The Slovenian covered the mythical 13.1-kilometre climb, which averages 8.1%, in 35 minutes and 27 seconds at the end of stage 19's 128km run from Megève. That obliterated the reference mark of 36:50 set by Marco Pantani in 1995, a time so revered that generations of climbers had been measured against it and found wanting.

Pogačar's margin over the Italian legend, more than a minute, is startling given how much faster professional cycling has become in the three decades since, with better roads, lighter bikes and radios replacing the primitive conditions of Pantani's era.

The victory was his fifth stage win of this Tour de France, underlining a level of dominance rarely seen on the biggest stage of the sport. It came after UAE Team Emirates-XRG's leader had trailed the day's breakaway by more than three minutes on the road to the foot of the climb.

He hunted the escapees down methodically before launching his decisive attack roughly 11.7km from the summit, on the lower slopes where Alpe d'Huez's switchbacks first bite. From there it was a procession, the Slovenian pulling away in front of the thousands of fans who had turned the mountain into a wall of noise.

Lenny Martinez, riding for Bahrain Victorious, held on for second place, with Richard Carapaz of EF Education-EasyPost completing the podium after both had been dropped inside the final kilometre of their own escape.

Behind them, the general classification picture barely stirred, because there was little left to contest. Remco Evenepoel, still the closest challenger overall, could only finish sixth on the stage itself, 2 minutes 40 seconds slower than the man in yellow.

That gap on the day stretched Pogačar's overall advantage to 7 minutes 11 seconds heading into the race's final weekend, a cushion that all but guarantees him a fifth Tour de France title barring disaster.

Isaac del Toro sits third overall, 9:42 down, while Paul Seixas is fourth and now just 24 seconds behind the Mexican rider in the fight for the last spot on the Paris podium.

Two stages remain, including one more high-mountain test on Saturday before the traditional processional finish on the Champs-Élysées. For Pogačar, Alpe d'Huez was less a contest than a coronation — a record that had survived Lance Armstrong, Alberto Contador and every other great climber of the modern era finally falling to a rider who, at 27, is redefining what is possible on two wheels.
