I'm not gonna bother with data right now but, I'll say that it's been cold here too. Hard freeze warnings for the last 2-3 nights. I've been riding my new cyclocross bike since I got it a few weeks ago. I've not only been using it to commute but, also to do cx training races (the last and coldest last nite) and to get 10th in the Little Everglades Ranch State Championship "C" race this past sunday.
As to cold weather gear, I was warm enough during the race last night and it was in the 40s. I did almost cough up a lung after from dry, raw sinuses (indoor heating) and the cold air during the exertion. I raced in my new tights, smart wool glove liners, wool socks and wool skull cap. Saturday's cross race in Gainesville should by closer to 70, that'd be nice. Ya gotta love Florida, we can easily have a 30 degree difference in daily high and low.
Almost forgot, my new Serfas True 250 lite worked great too. Check it out.
