This weekend, 22-year-old cyclist Egan Bernal became the first South American in history to win the world’s most famous bicycle race.

“I cannot believe it,” Bernal said in an interview. “It’s just incredible. I am sorry. I have no words.” And it is hard to believe, the Colombian cyclist becoming the youngest Tour de France winner in about eight decades, unseating frontrunner Julian Alaphilippe in the final stage of the race. Bernal’s teammate, Geraint Thomas, was last year’s winner, and came in second as the two crossed the finish line on the Champs-Élysées on Sunday.
