I wonder if Froome is using his exemption for asthma during this tour? I think this is an unfair advantage that someone can take a drug to help them perform. Should be no medical exemptions for anything. Fair playing field. If an asthma medicine can help you perform better, even if it is to a "normal" standard, it is enhancing performance. This could make a big difference in performance but because of the exemption, allows him to fly under the radar. Just my view. Don't beleive one should be able to use any banned/performance enhancing substance regardless of your situation. Go with what you develop in terms of unaided human performance. No medicine used what so ever!
