I finally got a commute ride in this week. Monday, I was tired from my fleche. Yesterday, I had a doctor appointment in the morning, so I drove.
This morning, it was 66 degrees with a howling south wind, which is a tailwind on my ride in to work. However, halfway to work, I hit the front that was coming in, and fought a strong headwind the rest of the way. It was 71 degrees with a strong northwest wind as I rode home.
Because my commute is 25 miles round trip, and the fact that I do long randonneuring rides on some weekend days, I don't try to ride to work every day. I've commuted by bike 37 times so far this year.
