Winter Running???

I am currently in "training" for a half marathon. Annie and I have been running together and we hope to be ready by may, to run from wayzata to excelsior without wanting to die at the end. But lately, with this cold front, I've noticed that my desire to go outside to run has diminished some. We've been so lucky this winter and somedays, it feels like spring. But on days like today, when it's 7 degrees and windy as hell, do I just bite the bullet and go outside? or do I save myself for another day and lounge on the couch in the warmth of my home? If I want to do sufficent training, then I guess I have to bundle up and go outside. I don't really know if I'm cut out for this, but I guess I'll find out.
