I say that as a 13-year veteran of winter running.
It's no secret that I much prefer the heat (and even the humidity) of summer. As an Iowa gal, though, cold winters are my reality for several months every year. Although I do a fair amount of whining and complaining about the winter weather, I don't let it keep me inside (much). My glass is always half full, even in the midst of cold fingers and frozen toes, because every run is a blessing.
