Faced with deep winter, the unfortunate question becomes, how bad do the jim-jams have to get to drive us out there where we can do the actual running? All you want is a nice relaxing run, and the atmospherics insist on turning it into the next thing to a polar expedition. Deep winter may not always present the most salutary conditions for runners, but think of it this way: change is what keeps us fresh too. Go for a run, change your life. Sometimes it can work better in February than it does in June.
