OK, it's not really the 7th day of training, but it worked better for my schedule to rest today.
I went to Sports Authority today and bought a Princeton Tec head lamp. DH worried about me running with the flashlight. His concern was that it wasn't at the right height for cars to see. I also bought a warm head band and those glove/mittens at Target. So I think I'm set until it gets a lot colder.
