Tips from a flatlander:
1) Go aero in position and in attire. Wear very tight-fitting clothes and learn to stay in a tucked position as much as possible.
2) Check forecasted wind direction and plan your route accordingly; it is preferable to have the wind behind you on the way home.
3) Plan loop rides, so that a strong headwind is only against you for, at most, 1/3 of the time.
4) Ride with a friend or friends, and take turns pulling. Try to not call it "breaking wind."
5) Treat the wind like a long hill and make it your workout.
6) Suffer into the wind, and know that when it one day lets up, you will be fast as hell without it.
