The 32-year-old cyclist from London knew that his time as a professional was running out, and he wanted to make the most of his last few years.
Wiggins' new regimen had him starting much earlier than usual, training hard as early as November, according to The Guardian's William Fotheringham. During the fall, he worked as hard as he would during the season, which kept him in great shape and allowed him to be in the best shape of his life when the season finally rolled around.
Per Fotheringham, Wiggins also decided to race fewer times per season, but to try to win each race he was a part of. He enjoyed a highly successful season, during which he won many events thanks to this strategy, and was well-prepared for when he finally went to France.
Wiggins entered the event with very little pressure on his shoulders. He knew that he had already won many times during the season and that the Tour de France would not be the be-all, end-all to his season.
While a route without extreme mountains and with two long time trials certainly helped him, this new training was the key in his victory.
Wiggins won the first time trial by an impressive 35 seconds and the second by over a minute. He couldn't have done that without his new training, and that was the key for his overall victory in France.
Wiggins will next put his training to the test at the Olympics, where he will seek an Olympic gold to cap off the season. With his new training, who's to say he can't do it?
