On 22 July 2012 Bradley Wiggins made history as the first British cyclist to win the Tour de France.
Ten days later at the London Olympic Games he won the time trial to become his country's most decorated Olympian.
In an instant 'Wiggo', the kid from Kilburn, was a national hero.
Two years previously, however, Wiggins had been staring into the abyss.
His much-hyped attempt to conquer the 2010 Tour de France had ended in public humiliation.
Poor results and indifferent form left him facing the sack from Team Sky. And then he was hit with the tragic news of the death of his granddad, George, the man who had raised him as a young boy.
At rock bottom, Wiggins had to reach deep inside himself and find the strength to fight his way back.
Outspoken, honest, intelligent and fearless, Wiggins has been hailed as the people's champion.
In "My Time" he tells the story of the remarkable journey that led him from his lowest ebb to win the world's toughest race.
In his own words he reveals the personal anguish that has driven him on and what it's like behind the scenes at Team Sky: the brutal training regimes, the sacrifices and his views on his teammates and rivals. He talks too about his anger at the spectre of doping that pursues his sport, how he dealt with the rush of taking Olympic gold and above all what it takes to be the greatest.
