| Marc. I'm without a cyclocomputer too. But my commute is exactly 20 miles, so the math gets really easy. 1 hr = well, you get it. Shortest time home was 50 minutes. Wind at my back, temp around 60 traffic very light, hit mostly greens. A friend of mine also has all the computers and heart rate monitors, etc. If I'm not seeing stars or looking down the tunnel, I figure I'm good to go! |
