Well ... I finished. I wasn't what I expected, and I had previously done that route five times as a 200 (and another five times as part of longer brevets). But the day was gorgeous -- despite the headwind the entire way back.

Edit 2013/04/29:
"I wasn't what I expected" -- that was supposed to be: "
It wasn't what I expected".
However, I think the slip to "I" instead of "It" may have been more appropriate.
