Dang! Congratulations HLRme! I'm curious, by the end or middle of the run do you start to notice a difference in how the cold is affecting you? I ask because I have never run outside during the winter - only inside. I stepped outside my comfort zone, yesterday, in below 35 and didn't think I'd want to do it again, yet I warmed up towards the end and felt great! What are you noticing for you, and what are you saying to yourself, in those first minutes of bitter cold, to press on?
