PARIS — Head down and legs churning, Jonas Vingegaard crossed the finish line of the penultimate stage of the Tour de France on Saturday and cupped his hand over his mouth, as if to stifle a gasp. He had done what he had come to do, and his astonishing accomplishment was sinking in.
In only his second Tour de France, and only three years after becoming a professional cyclist, Vingegaard, a 25-year-old Danish rider, had sealed his victory in cycling’s most prestigious race.
His victory became official on Sunday, when the race concluded with its traditional celebratory ride into Paris.
