Very few things in world-class sport can be treated as a formality, but a gold medal for Wiggins in the individual pursuit in Beijing was one of them. Before the Games, Great Britain's cycling team held a training camp in Newport before flying to Beijing. Wiggins would while away the afternoons watching the Tour on television, not missing it a bit. During one of the mountain stages, Sutton told him: "You know, with the power you produce and the cadence you do it at on the track, there's no reason why you can't be up there with them."
Wiggins was not convinced. He'd tried it before, but had always been dropped. "No, you've only half-heartedly tried it," Sutton said.
At Heathrow airport, Wiggins saw Jonathan Vaughters, who told him the line about turning a miler into a marathon runner.
"He said he'd seen what I'd done on the track and couldn't understand why I kept getting dropped on the road," says Wiggins.
Once the Olympics were over, Wiggins was determined not to lose another two years. "I was 29, a bit more mature, and I wanted to see what I had inside me, whether I could do something on the road."
He asked his Columbia team manager Brian Holm how he saw the 2009 season panning out. Holm told him there was a place in the Mark Cavendish lead-out train for him, but that he couldn't be guaranteed a place in the Tour.
"That made my mind up really. I enjoyed riding for Cav in the Giro, and I completely understand why they saw that as a good job for me, because Cav can win stages in every race he does, he could win the green jersey. You'd be stupid not to build a team around Cav, but part of me wanted more than that for myself. I wasn't an integral part of the lead-out train anyway. I'd just be filling a space."
Much has been made of the post-Beijing fall-out between Wiggins and Cavendish. They fell well short in the Madison, leaving Cavendish as the only member of the British track team without a medal. The pair didn't speak for several weeks, but anyone who believes there is real enmity between them is mistaken. Sure, they wind each other up, but Wiggins sees Cavendish as a sparky younger brother figure, and will roll his eyes in mock despair when recounting the last drama to embroil Cavendish.
Garmin offered Wiggins a two-year contract, and a handsome one at that. Wiggins outlined his goals, but it was Sutton who urged him to see how well he could do at the Tour. To make the top 20 overall, he'd need to climb better, and to do that, he'd need to lose weight.
British Cycling's Matt Parker has coached Wiggins for several years, and it was him who did the calculations. "We've always known there's a road rider in there," he says. "Brad is a supreme athlete. He's an Olympic champion and world record holder, the power he produces, we knew he could climb well, maybe not in the first group every day, but definitely in the second, and that would give him a chance of being in the top 10 of the Tour."
Wiggins rode the Olympic Games last summer weighing 82kg. In the past he has ridden the Tour and Giro d'Italia at about 77kg or 78kg. The aim was to start the Tour this year at 72kg. It stands to reason that if you can produce 450 watts for 10 minutes weighing 72kg instead of 78, the gain in performance is going to be considerable. Enough, Parker says, to put him in the front group on the climbs.
"You develop a lot of muscle mass, particularly on the upper body, while training for the track over the winter," says Parker. "We wanted him to lose that, but to do it slowly, so that it didn't affect his power.
"Everyone has focused on the weight loss, but it's not been radical. It's been managed very sensibly and safely. If you lose weight too quickly you don't maintain the power and you can affect the immune system. Radical weight loss in sport is never good."
Working with the nutritionist, Nigel Mitchell, Wiggins began to lose weight at the start of the year. He went gluten free in January and February, stopped having sugar in his coffee, would do training rides without having breakfast to get his metabolism to work differently, and he'd do longer training rides.
And the beer? "I haven't had a beer since January," he says, rather longingly. "I've had a little bit of wine, but the carbs in beer are not what you want, so I've cut it out."
Wiggins started the Giro d'Italia under 75kg, then the three-week stage race did the rest. And his climbing improved too. In the first ten days he was regularly with the front group on the climbs, although his team-mate Christian Vande Velde told him he was doing it the hard way.
"On Alpe di Siusi, I was sitting on the back of the group and Christian was watching and he said ‘the amount of work you did that day was worthy of a top five finish'. Being at the back meant that every time someone got dropped, I had to ride round them and close the gap."
Riding at the front makes life so much easier, but you have to earn your place there. "They [the other contenders] don't want you there if they think you're going to go pop any moment. They want you out of the way, because they last thing they need is you sitting up so they have to ride round you."
The Giro, though, swelled Wiggins' confidence. "After that I thought ‘maybe I can
do something at the Tour'."
The tests he'd done suggested he could. "In a ten-mile time trial I averaged 482 watts for 18 minutes, and if I did a 30-minute test on a climb I'd be averaging 475 watts. At 71, 72kg that gives me a chance. It's a level playing field now, or so they keep telling us, and I believe that, so why not? I'm in the bike race, we've all got two arms and two legs, so why not? If I blow up one day and lose 20 minutes, so what?"
