Heavy rains coming and so is the cold...

We are due for heavy thunderstorms today and then the cold will creep in behind it. I'm on my taper before my 10K, I haven't run the distance in 2 weeks because of a race last weekend, I couldn't get a longer run in. It is now set to be about 35 degrees that morning. I don't like the cold, 40 and I'd be happy...45 is what I consider perfect running weather. I know I should enjoy this as soon it will be HOT! I am thinking about hitting the gym to walk 6.2 tonight...only because I feel antsy and need to do SOMETHING, ANYTHING to maintain my sanity!
