So happy to be going back to family and friends for Xmas but dreading the cold weather running. I’ve even signed up for my first ever 5k in a parkrun on the 30th as I’m on Week 8 right now. I’m going to need to buy a load of warm running gear as I only have shorts, running shoes, and vests at the moment. My biggest concern is the cold icy air. My lungs just aren’t used to it. Any advice welcomed.
