It's the rules that are wrong. Do not allow any TUEs. If you have a condition that prevents you from competing then tough shit. Sure, it's not your fault you've got asthma but then it's not any of the paralympians' faults that they're unable to compete in mainstream sports either. It's just tough shit.
I'm confident that paralympians are also allowed TUEs. I agree that the circumstances around Wiggins' injections are suspicious but suggesting that unwell athletes should be refused the most effective treatments if they wish to compete is ridiculous.

However don't you think it strange that his asthma has never been mentioned. He could have been a role model to so many suffers that they should not get down and they too could be an Olympic ahampion one day and still despite having severe asthma compete at the very top in a massively demanding aerobic sport. However only now does it come out that he is an asthma sufferer.
