4 hr ride in the wind

Today we had sustained winds at 25 mph with gusts AVERAGING 39 mph.  That equals a tough ride.  A 4 hour ride at that.  At one point heading into the wind out by Lake Benbrook in a flat section without any trees around I was going just about as hard as I could with my HR screaming I looked down to see I was going 7 mph.  I typically cruise 17-18 in that section.  Not to mention the wind, but it was the warmest day that I had ridden this season at 91 degrees and 65% humidity - bring on Louisville! I lost almost 6 lbs on that ride.
