I set out to do a 50 mileish ride out on the country roads.
I did 22. It was out and back. The first 11 i averaged 9mph. At one point I was out of the saddle peddling down hill doing 8mph. I turned around and headed back. The next 11 I averaged 27mph.
Obviously it was windy. I feel spent but like I got short changed as well.
I’ve had too many of those days to count this year already. It’s be the windiest spring I can remember out here in the desert.
It was one of those days here as well for MissP and my 100K ride this morning. Wind all over the place, cool temps and on and off showers. Some roads where muddy and manuer covered - nice!! Fortunately for the worst of the wind we were in a big group and then when we where on our own we had a tail wind 
Saw some tri-freaks out riding with next to nothing on - what is with that?? Just took the powerwasher to the bike afterwards.
I had one of those rides just today. I set out to do a 40k TT effort on an out and back course. On the way out I think I averaged 17mph. On the return trip I averaged 32mph!
