Headwind on the way to work. We start a half hour later in the Winter and Fall and today was the first day. I dealt with a lot more traffic. It's crazy how one half hour can make so much of a difference. I went from starting at 6:30 to 7:00. Best part is I saw four other bikers! Only one of them was a Ninja who was incidentally riding directly at me going the wrong way! Good thing I was paying attention. I also noticed my crank starting to make a sound every few rotations. Still havn't figured out what the problem is.
The ride home was way to easy and short. I wanted to keep riding.
