4th commute for me. This one went very well. For the first time I used a handle bar mirror, and being able to look behind me really made the ride a lot more relaxed. Before I had the mirror, I would constantly turn my head to look for a car behind me, but with the mirror I can concentrate on just riding and what's in front of me. The weather forecast says 50% chance of rain today, but so far the sky looks pretty clear. Let's see if that changes by the time I have to ride home.
Before I started commuting on bike, I used to cycle at night in a nearby park for 1-2hrs. However, now my legs are getting sore on the ride to work, so I'm going to switch the night time exercise to just a brisk walk until my legs adjust. I did this for the first time last night, and ended up walking roughly 4 miles.
