Weirdly enough, I really LOVE
Weirdly enough, I really LOVE running with a snotty nose...3 miles will clear up my sinuses better than anything. It's the only time during a minor cold when I'll be feeling great (probably because the body is distracted from fighting the disease, & working on the run instead.) But of course it can't last and the moment I end my run I'll be all blocked up again. Boooo.
But of course I only run when it's a very minor illness.
The best thing is I only get minor colds usually so I run through them almost every time. Sore throats keep me on the couch, though, and stomach flu, and regular flu. Colds demand some time outside in the fresh air, especially if the air is cold it feels so good.
But yeah, keep those runs short!
