Commute home yesterday was brutal. Very strong headwind. On a 4 mile stretch of -1.0% grade - slight downhill, I was barely able to maintain an 11mph average. Some gusts kept me under 9mph. In the morning, along this same stretch, (going uphill, of course) with no wind, I average around 14.0-14.5mph usually.

I've never actually commuted by bike 2 days in a row, until now. Today my ride to work was a little chilly (low 50's), and I felt sluggish - especially during the first 5 miles - but I made it to work in the exact same amount of time as yesterday - to the second. 49 minutes 0 seconds for a 10.3 mile commute. I've been taking it easy to try to save me knee. My commute is usually around 43-44 minutes.
