Yeah I think they just need to re draw the lines. Sport enduced asthma is a real thing of course. You don’t need a TUE to use an inhaler like Froome does. When you’re arguing you need steroids I think that’s too much.
We need to be careful though that we don't exclude people, or make them feel like they can't compete, just because they have genes/hormones that limit their natural abilities. During my school days (and I didn't know I had asthma then so never impacted me) there were kids who were excluded from sport just because they had asthma - never given a chance, back of the queue etc. We already have an issue in this country with kids getting fat so I don't think we should be giving them an excuse not to exercise and take part.
WADA says asthma drugs don't improve performance (and they don't need a TUE anyway) so they shouldn't even even come into the discussion, at least no more so than a vitamin tablet or ibuprofen for headaches. If these drugs can allow people to compete on an equal basis that has to be good ... no?
As for Brad and the TUEs - I also read into it that they are/can be used in that grey area, but he was 100% correct that he'd rather know about a rider who has requested and been approved a TUE, than those riders who take stuff outside of comps and no TUE. TUEs are at least signed off so if the authorities are not happy then they shouldn't be signing off the TUE in the first place.
I think for those people who are lucky and don't need medication then they will always argue that no one should be allowed to take anything at all, whilst those who need medication will always argue the opposite. But, I think we all agree that we don't want anyone taking drugs that they don't need or is purely to cheat and enhance their performance.
