Also a daily runner (6.5 years) - the worst time to run is when you have a head cold. The impact from the run just pounds throughout your skull. I have run when I had influenza and Covid. Only one mile at a time, up and down my driveway, but it wasn’t pleasant. But it was really only bad for a day or two, and for the sake of the running streak, you run (jog/walk) your mile and you’re done (and you collapse back to sleep). Then, once you’re starting to feel a little better, the feeling of running just one mile (when you’re used to running 3 or more) is the hard part.

I also ended up training for a marathon while I had a mild pneumonia. I had no clue until I saw my doctor for a routine checkup.

When you have a running streak like this, you find ways to make it work. You’re often running with some kind of a knock, be it a cold, or some knee pain.
