Doctor friend of mine explained it to me one time, it isn't the same with everyone but it's not uncommon - don't remember the name of the effect she described was though. When it gets sub 20 if I run too long I turn into a wheezy wreck once I get home. Lots of sneezing, uncontrollable runny nose, difficulty breathing, face feels like it's on fire, headache, etc. - has to do with inhaling the bitter cold air. Snow dictates exactly how far I go, but I'll max at 4-5 miles when it's between 10 and 20 and only do 3 if it's less than that. Sucks because the temperatures don't force me in otherwise, I love running when it's colder.
After getting bit that one time, I told myself I'd Karate Kid kick the dog in the head the next time. But what can I say? I guess I just don't have it in me.
I dont really know what I am doing.

You too, Juxt!!!
no kidding. I'm sweating my one 22 miler and this guy is basically doing that 3x a week.
