I just think that Sky is a two year ahead the rest of the teams when it comes to professionalism, traning and nutritiion. Believe me, there was plenty to gain here. For so long cyclists have had months off training, som even bing drinking, eating wrong etc. Cyling have been way behind other endurance sports.
Cyclingtraining have been extremely traditional. Up untill now. Give it two-three years and the other teams will have closed the gap.
And remember, GB have put millions and millions into sports science for the past couple of years preparing for the olympics. Team Sky is apart of that research and they are gaining a lot from it.
Others have to learn. And they will.
