How I beat the winter blues

I used to get extremely tired in the winter. The winter blahs is you will. I did not like that. So a couple of years ago I figured out what works for me to beat the winter blues. Running! I guess it does not have to be running, any exercise outside will do. Sledding with my kids counts too. But obviously for me running is my favorite. So I am looking at some crazy winter races just to keep me motivated to train and run harder. Any one else have way to beat those winter blahs?
