I agree with all this. I was NOT prepared for the cold, since the year before had been so warm. I had throw-away arm sleeves, but that was about it. Cold to start, but warmed up quickly. However, the cool-down in the misting rain after finishing was BAD! REALLY wishing I hadn't tossed the arm warmers but tucked them in my waistband or something. Anyway, moral is to be prepared for anything - just in the 2 days before the race the weather changed drastically. Friday I wore shorts and a sleeveless shirt. Saturday I had to wear jeans and a long-sleeve shirt and sometimes put on a light jacket. Bring it all!
