There are ways to cheat the wind. One way to do it is to find a route that is wide open going out with the wind and protected by trees or terrain coming back against the wind. Another way is to go out at sunrise against the wind. Because the winds tend to pick up later you should have a stronger tailwind coming back than the headwind you rode into. Alternately you can go out late in the day with the wind and return near sunset as the winds tend to die down late in the day. Lastly if you are very lucky you can time a cold front and get tailwinds both ways.
