Although the weather is a beautiful -15C outside, we had a warm spell about 10 days ago, that brought rain, freezing rain, then the temp dropped and we got a fair bit of snow. Now the snow lies on top of a nice layer of ice! Makes running very dicey! Although my form stays intact, I find it very hard to relax, especially my upper body. Find my upper back is tight between the shoulder blades. BTW, I live in the country, and snow plows are like Pope's teeth in a whore house!! Me thinks my massage therapist might be getting a call in the very near future!!
