This thread is mildly confusing in the sense that I feel like I'm in math class and got bored. With that said, in a nutshell, if there is a 20mph tailwind vs a 20mph headwind, do they even out or will you still exert much more going into the headwind than going with the tail wind?

It just seems like that when I ride on a windy day, i'm much more tired than the same ride on a still day but I would have thought that the going against vs going with would have evened out but it doesn't seem like that.
