Allergic to cycling ?

[Minusorange]

All through out winter and into spring I've been constantly getting a runny nose when cycling, it's getting really annoying, it can't be hay fever because I'm not sneezing and eyes don't feel irritated it's just a constant stream of snot forming in my nostrils.

It ONLY happens when I cycle, doing anything else I'm fine so I have no ******* clue what's causing it, any one have an idea to what it may be ?

I thought it might be cold weather but even when its been mild (the few days) and even today with it being shorts and t weather nose was still runny, will see how it is over the next few weeks when it gets warmer though, just seems strange it only happens when I cycle

And not riding anywhere with busy traffic (live coastal rurally) so I doubt it's anything to do with emissions

Thanks for the responses good to see I'm not the only sufferer of a runny nose, hopefully with it getting warmer it'll stop soon
