Bradley Wiggins hasn't always been the easiest of athletes to interview. In the past he was known to be spiky, difficult even. But as I watched him fulfil endless media responsibilities out at his training camp in Majorca I was struck by how engaging he was, how open and how assured. Wiggins finally gets it.
"It's probably going to be my defining year, in a sporting sense," he told me. "It's going to be the difference between having been a good cyclist...or having been a great cyclist."
At this point in his career he could easily have holed up himself up in his Spanish hideaway where he's putting the finishing touches to a training regime that will make or break his summer. He's about to embark on the race of his life with the Tour de France starting on June 30th.
He would be the first Briton to win it - and he's in the form of his life, peaking at just the right time after an incredible series of wins that has seen him become the bookies favourite for the gruelling test of endurance.
But after he crosses the finishing line there is no time to rest. From Paris he will head to Surrey to the Olympics holding camp where he will then attempt to help Mark Cavendish win TeamGB's first gold of the Olympic games in the road race. Three days later he'll get his own shot at gold in the time trial.
If everything goes well, he'll have the Tour win that he and Britain craves, plus a fourth Olympic gold to add to the Wiggins mantelpiece. One false move though and all the hours, sacrifice and pain would have been all for nothing.
No wonder he tells me that this is his defining moment.
