My Monday run was in basically those very conditions-- such a relief after our never ending summer! I wore wool socks, shorts, short-sleeve shirt under a lightweight, loose long-sleeved shirt, and baseball cap. I find the cap a necessity for keeping the rain off my face. The shirt's sleeves are so long that they came down over my hands; if they hadn't I might have worn light gloves/mittens (my hands always get cold).

I love running in a light rain, so long as there's not much wind. When it's wet and windy and cool, that's what gets miserable...
