I have a 5K tomorrow morning and I was laying out my clothes this afternoon. That way, I don't have to run all over in the morning to get myself ready. Here is what I wear to run in when the race-time temp is below 20 degrees....
Second layer is a set of cuddleduds....pants and a tank top.
Third layer is my thin, long sleeve tee and a pair of black running tights. They aren't technical running tights, and I would really like a tighter, thinner pair; but these will work for now.
Fourth layer is a dry-fit tee and a pair of shorts with pockets. The pockets are key in the outer layer so that I can keep my chapstick and a piece of gum at the ready. My ipod and car key goes in my Spi-Belt.
NEDA hoodie (that can be taken off and tied around my waist if I get too warm), Green Bay Packer stocking cap, green 'neck-gizer,' gloves and my shoes. The gloves usually come off at some point and end up in the pocket of my hoodie.
