Youthful Bernal lifts Colombian cycling to new heights
Bernal was born in Bogota and grew up 42 kilometers north in Zipaquira, a mining and agricultural town, which sits at an elevation of 2,650 meters in a valley surrounded by mountains.
His father was a watchman and his mother graded cut flowers for export.
As a child, Bernal took up cross-country biking and trained in the nearby woods under the guidance of Fabio Rodriguez, a Zipaquira native who had ridden in the Spanish Vuelta.
Young cyclists can hear the roar of a chainsaw and see other youngsters earn their living by cutting down huge trees and carrying them on their shoulders to trucks.
"That's why I keep telling kids that it's better to get up early and train by bike," Rodriguez told AFP.
Bernal dedicated his victory to Pablo Mazuera Zambrano, "my first manager."
Mazuera told AFP that financial pressure almost persuaded the youngster to give up, despite a silver in the world junior cross-country championships in Norway in 2014 and a bronze in 2015 in Andorra.
"He came from a very low income family," Mazuera said.
"He started at university, in media studies," said Mazuera. "He got a scholarship. He wanted to quit because he wanted to be a journalist."
After the finish of the penultimate stage on July 27, Bernal thanked Mazuera.
"At one point, I stopped riding," Bernal said. "He told me to try. Thanks to him I'm riding a bike. He's guilty."
Bernal was recruited by Italian Gianni Savio who needed a climber for his Androni team. After two promising years, Sky swooped and bought his contract for 250,000 euros.
"He's a good person," Savio told AFP. "He has kept the humility he had when he joined our team."
"Geraint will be our leader and my job is to help him," Bernal said.
Former boss Savio praised Bernal's attitude.
"He showed all his intelligence," said Savio. "After his victory, he said right away that he would work on the Tour de France for Geraint Thomas. Others would have launched a claim, but not him. It was then the Ineos team said they would have two leaders."
In the 1980s, Colombian Fabio Parra finished as high as third in the Tour and compatriot Luis Herrera won the 1987 Vuelta.
In recent years, Nairo Quintana, winner of the 2014 Giro and the 2016 Vuelta, and Rigoberto Uran have finished on the Paris podium. But while Herrera, Santiago Botero, Mauricio Soler and Quintana all won the polka-dot King of the Mountains jersey, no Colombian had finished first overall in the Tour.
At just 22 years old Bernal has changed that.
His victory also marks a changing of the guard at Ineos.
As Sky, they won six of the last seven Tours with Bradley Wiggins (2012), Chris Froome (2013, 2015, 2016 and 2017) and Thomas (2018). All are British and all were over 28 when they won their first Tour.
"He has the physique of someone older," Savio said of Bernal.
Last year Bernal was the loyal domestique to Froome and Thomas, always the last man pulling the Sky leaders up the steepest slopes.
After Bernal finished 15th overall, team boss Dave Brailsford called the Colombian "the man of the match."
On July 25, Bernal chased stage-winner Quintana up the 2,642-meter Galibier.
"When Bernal made the attack, he was able to take advantage of the altitude," Quintana said. "We live at 2,700 meters."
