Is there a hard-and-fast rule about whether or not to ride when you're coughing up brown stuff, however little? About a week ago I cought a very minor cold, so feeble I hardly knew i had it, and this has left me with a very minor cough. I only cough a few times a day, and one or two of those coughs bring up very small amounts of brownish phlegm. I feel fine otherwise. I want to get back on the bike ASAP, especially since the weather is calm and dry at the moment, but would I be risking it getting worse if I go out before it completely clears up?
Thanks for any input
