Tadej Pogacar overtook countryman Primoz Roglic and is set to become the youngest Tour de France champion since 1904, the second-youngest in history and first Slovenian champion.
Pogacar, who turns 22 on Monday, overcame a 57-second deficit to Roglic and won Saturday’s penultimate stage, a 22-mile time trial with a finishing four-mile climb.
Sunday’s finale is the traditional ceremonial ride into Paris where the overall leaders don’t attack each other.
Pogacar is riding his first Tour de France and in his second season as a professional cyclist.
Last September, he finished third in the Vuelta a Espana, one of three Grand Tours, which Roglic won.
