Agree. Rode on Jan 28th, as I thought it would be OK, 60 miles, bad move, paid price with it getting on my chest, laid up until Feb 20th. Look after yourself.Don't do it.
If your bike was broken you wouldn't ride it till you had it fixed, treat your body the same or you'll risk making yourself worse.
Been there, done that.

i'm sure I remember an old cycling saying 'take it up the road' .....and leave your cold/cough out there, perhaps a light scarf to stop the cold air hitting your lungs could be a good thing.
