I was tired but I pushed myself to the point that my muscles started to burn on the uphills. It was the coldest weather I've encountered in about a month with temperatures hovering right around the freezing point. When I coasted into my driveway, I noticed that I had developed a bit of frost on my gloves.
I wouldn't have imagined riding in this weather 3 years ago and I wouldn't have imagine working in it 5 years ago.
