The 32-year-old has endured a punishing yet hugely-successful summer schedule which saw him become the first British rider ever to win the Tour de France, and then take the gold medal in the men's Olympic time trial.
Since then Wiggins has been spending time with his family, and has also taken part in a handful of charity and exhibition rides, but doesn't feel his form is good enough to challenge for the time trial rainbow jersey in Limberg.
He said: "I haven't done the training I need to do to win something like the World Championships.
"I've set a precedent now and to go there to get third or fourth just wouldn't be right after everything that's happened this year."
Reflecting back on his Tour de France success, Wiggins has also revealed that he didn't enjoy the arduous three weeks of competition which saw him claim the biggest prize in the sport.
As well as pushing himself to the limit every day on the road, being in the yellow jersey for two weeks meant Wiggins had to fulfil various media and commercial duties, and also carry the hopes of a nation on his shoulders.
"When I look back on it I have bad memories of the Tour," he added. "I enjoyed the last weekend, winning the time trial and going into Paris, but the rest of the race and everything that goes with the race, it wasn't an enjoyable experience.
"The Olympics was something else and it made everything for me because it was a real joy to ride."
Wiggins's next race for Team Sky will be at the Tour of Britain, which commences in Ipswich this Sunday.
