Hi, FastFwd01. I live in the Denver metro area and ride most days. I have been wearing shorts and a light wool polo shirt this week. If I were doing the Denver Century I would have a light wind shell in addition to the aforementioned clothing. The wind shell would be useful in the morning, and maybe on the descent of Lookout Mtn, depending on what time of day that is. The road up Lookout Mtn is all in the sun; incoming solar radiation at mid-day is a big component of the heat here in Denver. That being said, on Sept 25th the amount of incoming solar is a lot less than in the summer. You've probably already been advised about hydration . . . and sunscreen.
