You may have already done so, but have a hayfever tab or a piriton before running, or if it doesn't help, go to the doctor and get an asthma check up and say that you're a high level athlete and that you suffer at high exertion. A blue reactive one isn't a banned substance and you don't need a TUE for it. Hope it clears up bud
Cheers! Think it's a bit of a slippery slope with inhalers really.. I'm planning on adding a few antihistamines to my current ones, should probably do the trick even if it's only hocus pocus psychological..
Yeah fair play, don't want to disrupt the routine too much! Sounds like a good plan though, hope it works out
