This was my ride tonight:

Hills are nothing new to me. Initially, after riding on Zwift for the past few days, my bike felt really light. I also realized that I don't ride as fast in real life, my cadence is slower, & I don't push as hard. Also, as was mentioned above, there are downhills & flats where I get a little break, while I just continue to push on when using Zwift. During tonight's ride I also noted how much wind there really is when riding and all I have to say is WOW. The concept of a wind tunnel isn't far off.
