I believe that the whole matter will be cleared up quite easily. No, salbutamol is not a PED. Yes, he had double the permitted dose on ONE day only, when he had been suffering more than usual. As one BBC reporter said he is renowned for coughing and spluttering during post-stage interviews, such is his condition.
Hand on heart I believe Froome took it without realising the possible repercussions. As another expert has said, adverse conditions such as dehydration can render the body unable to metabolise certain medications at their normal rate.
Froome would have been tested every single day during the TdF and La Vuelta.
His case and that of Bradley Wiggins are poles apart. Wiggins took advantage of his condition and used a TUE in order to use a PED. Froome and the rest of Team Sky were apoplectic when the truth came out.
Froome has nothing to hide, he has always been open, honest and publishes his training/clinical data for scrutiny and I’m confident he will be cleared and vindicated.
