man, that was freakin cold!
I can deal with soreness, but I don't like running with pain, if I don't need to. So, I went out planning a short run for today, just to see how things would be.
My issue is that I just started a new workout routine in the evenings (Insanity). Being very sore left me not knowing if I would be able to run at all. But at least I had no pain in my knees.
So I ran 4.5km and it was tough. I kind of shuffled and hobbled it, but I see that it was not so bad. Part of that was also stiff limbs from the extreme cold.
