I don't think the course Bradley Wiggins won on was tailor-made for him. He won because he has great talent, a great squad to support him and a back-up team that combined Sky money and olympic training and nutrition expertise.
Other teams have caught up on the Sky training regimes and Bradley has got a bit older and a lot richer.
When I watched the interview where he said he's finished with the road, it wasn't said with as much bitterness that came across when it was initially published in bald newsprint. He is just facing the facts that he is extremely unlikely to win one of the three major tours any more and others will be selected before him. When he pulled rank and declared himself for the one-day spring classics, he fared worse than Sky, or he, expected.
He can't have been completely cheesed off at Sky because he has reportedly signed a new contract.
In order to revert to track cycling, he needs a different musculature. That's the main reason why he's saying goodbye to the road. It will also give him more time to exploit his commercial interests and more time at home with his family.
Bradley Wiggins got thousands of Britons interested in cycling and taking it up to keep fit.
Good luck to him on the track.
