I've noticed that the tailwind never quite makes up for the headwind, though, particularly in urban/suburban riding. The headwind can kill not just your speed but your willingness to sprint for lights before they change, or to swing out to pass a bus. The tailwind going the other way never seems to quite compensate, probably because of the number of situations that force you to limit your speed anyway, wind or no.

Obviously I'm talking more about urban/suburban riding with lots of traffic and intersections. Which is most of my miles, so what else would I have to talk about?
