So,.. the forecast was for a high of 65f... I'm gonna' ride...
...a series of miscalculations...
-forecast was off... high of 60f...
-that's the high... (it only lasted 10 minutes)...
-15 to 20 mph headwind...
-2k elevation change...( I figured it would make a 5f difference... nope, more like 15f)...

...ended up about 40 to 45f... with a headwind, plus 60mph average speed... (wind chill chart don't go that high with wind but, 40f at 60mph = 25f)...
I got cold...
(Arizona cold - that's a thin blooded, wuss, kinda cold)... ...
... and it was still 100 miles of great fun...  ...
