One Wednesday back in early April I had my wife drop me off 15 or 20 miles from home and rode home with the wind. We had three or 4 straight days of east wind anywhere from 15 to 30mph............got tired of it after Monday and Tuesday and rode home with the wind that Wednesday afternoon. Does wonders for your average speed for that day!! Normally though I will ride into the wind going out and with it coming home. Lately have been taking off about 6:00 AM before the wind gets a chance to really start.
