I went for a run last week. It was my first one in almost a week since I caught a bad cold, or pos­si­bly even the dreaded piggy flu (fever, sore throat, hack­ing cough). What­ever it was, I was com­pletely out for a few days and didn’t feel up for much of a walk or run for a few more after that. I don’t sup­pose I was nec­es­sar­ily all bet­ter the other night when I went out for a run, either.
