Hello, my name is Raven... and I'm an addict...

Yes, I still ride when sick - but as the others say, if it is chesty/below the neck, I don't. Like others have said here already - this is dangerous and potentially it is life-threatening.

I have known two people now who, desparate to do events they had entered in, took pills to disguise their symptoms and ended up very sick after the intense riding of the event because they had placed such demands on their (but because of the cold/flu tablets, they hadn't realised how unwell their body was feeling). One ended up in hospital - these are both healthy, reasonably fit 30-something-year olds.
