Very strong ground winds!

I checked the weather report for today and it said winds from the North at 11 mph. Well they must be measuring the winds from the top of a building or something as the winds down near the ground are much, much stronger. I never noticed this until last season and it seems to be more pronounced this year. I rode 17.05 miles in 1 hr 18 min at an average speed of 13.4 mph and a max speed of 23.2 mph. I burnt 808 calories and my average heart rate was 133 bpm. My elevation gain was 724 feet. The ride was uneventful but still a nice ride. The temperature was 76 degrees and the wind was from the North.
