I rode the Wine Country Century last weekend with my daughter (who flew out from Kansas City). My wife rode the 35-mile route, having recovered from her recent crash.
Had a great time, and my training paid off. The weather was perfect -- much hotter than I am used to, but OK with the breeze. The scenery was a combination of forests and vineyards.
My daughter held me back a bit at the beginning, but if I'd gone faster I would have suffered more at the end.
I learned that my bike shorts' fabric has worn away in the back such that it is essentially transparent -- something you don't know unless you ride with someone you know.
My daughter told me I'd be the only one without low-rise socks, and she was right.
We got off course at one point, resulting in a shortcut, then did a "penalty lap" so we'd still come out to 100 miles. However, then we got off course again and added a few miles, so we ended up with a total of 102.
