Wiggins admitted that his fourth place in the 2009 Tour de France was a fluke.
"It was fluke in the sense that it wasn't planned. I fell into superb form and was riding on cloud nine for most of the race and held onto fourth place," he said.
"This is huge learning curve. This is the first year I've tackled it like this full on. It's easy to think you can improve and get it right. I recovered well from the Giro and did some good stuff in training that suggested it was all pointing in the right direction but obviously it's another thing producing it in racing and holding it day in day out. Is another thing all together. Then you can't account for what everyone else is going to do."
