didn’t Boardman have some sort of home-made altitude room in his house when he was riding?
As for Froome leaving Sky, it seems quite probable unless they’ve given him answers in private to the whole Wiggins-paper bag debacle. He’s being asked loads of questions related to BC/Team Sky doping that are nothing really to do with him and I’d imagine after a while it becomes too much.
Can’t say whether or not BMC would make sense but if they let TvG go as seems likely as they supposedly agree about him as a Grand Tour leader, they have a spot for a 2nd GT rider. The fight over who gets the TdF would be interesting though. Maybe he could go to Trek though, Contador can’t be THAT far off retiring.
All that said, Froome says the BMC story is bollocks. Maybe BMC are trying to push down TvG’s salary requirements. They must be paying a lot for Greg van Avermaet as well as Porte.
