I have 40 mile round trip suburban commute, equally hilly in both directions. I originally expected my morning commute time to be faster than my evening commute time, because I would be less tired in the morning than the evening. Also, there's less traffic in the morning than the evening, so the traffic lights tend to be more in my favor in the morning. But my evening commute home is consistently faster. I think that's because the workday is over and I'm pumped to get home. What's your experience?
