Something certainly went wrong but I'm also sure of Froome not knowingly 'breaking the rules' after some of the comments he made around Jiffygate. I recall statements he had to retract/apologise from fear of tarnishing Skys reputation even further?!
Froome being Froome, he was separated from much of the ingrained 'bad' dealings around cycling of the 90's and 00's. He was geographically separated and professionally separated from the teams, riders, coaches and doctors which dominated much of the doping stories. I wouldn't say he was ignorant to it, but he was certainly an 'outsider' to it and the things which went on. I recall a mention in one of his books (The Climb?) where he recounts a story of speaking to one of his Barloworld teammates where he commented "that guy's quick, who's he?" when seeing Nibali and his teammates being flabbergasted. So much of the cycling culture, training methods and coaching was foreign to him!
No theory, the data is up on
Strava on a verified account he's used before. 2300+ miles so far this year!
I'm fairly sure it's a PR exercise, possibly initiated by him as he's always been fairly open about his training, routes and riding. He's very active on Twitter. I think it's Sky that have generally kept things very secretive. Even Pete Kennaugh is back posting up rides now, he did loads before joining Sky, then none when riding for them.
Unless they can prove it I'm betting we'll find out they used a nebuliser or some other way to administer it, as they've discounted the tablet idea I was originally sure of and are trying to hide/cover over it (as the doctor who administered it wasn't aware of the TUE requirement or something).
