Ride in was 41 degrees with a 7mph tailwind. Ride home was 50 degrees with a headwind. 23 minutes each way, go figure. 15.4 MPH average both ways. Back in October I got as low as 9MPH, so I guess I'm improving slowly but surely. I might try getting off the major arterial roads to loose some of the traffic lights. Even if it is slower, I'll get more mileage!
