Bradley Wiggins opens up with full story on asthma, allergies and TUEs

" Wiggins explains what he says is the complete chronology of his symptoms
" Cyclist believes Brailsford and Sky coaches were fully aware of treatments

Sir Bradley Wiggins has for the first time given details of the history of asthma and pollen allergies that led him to apply for three therapeutic use exemptions (TUEs) to have injections of the banned corticosteroid triamcinolone. The use of the drug did not break any anti-doping rules, although they occurred immediately before major target races, but the 2012 Tour de France winner and nine-times Olympic medallist said he realised why the injections might be considered unethical.

In an exclusive and wide-ranging interview with the Guardian, Wiggins explains what he says is the complete chronology of his symptoms and treatment for those ailments, detailing why the injections were required before certain races but not others.
