Congratulations. How do you feel now another thing I do, the same as skiers, I wear a breathable cover, over my mouth in cold weather. This allows a filter to protect the lungs from cold air. I have a small narrow flask I got at a sport shop that I use for water after reading your blog. I put room temp water in it. However, as the weather gets colder, I’ll warm it up a bit. I find layering my clothes the best for me.i put a short slender ski warm jacket on, then a vest with a hood, winter but flexible material. Then I have a longer vest, very very lightweight with loose armholes that I open once I get hot. Then I can unzip the other vest as well if I get hot. Plus base layer of cotton short sleeved T with long-sleeved stretchy sport cotton over. I never unzip my first ski jacket only the two vests. I only do interval running and with a tuque and sometimes the added hood, it’s a warm one from my first vest, I never reach a shiver or get a sore throat. I used to before I did all this with the layers.
