Recently ran across two rides I did days apart that tell the story of wind. First one 200km down the Florida Keys to Key West, completed in 7 hours including stops, with a significant tailwind start to finish. Back north a few days later into the wind, 10 hours. I do not have power data, but my recollection is I rode hard on the downwind leg just because it was so frickin' fun. I worked hard on the headwind leg because I had no choice.

The difference was 3 more hours of perceived misery than hours of perceived joy.
