I'm going to be visiting Denver during the last week of August for business, and I'm bringing my road bike. I'll be staying at the city center, and I'd like to know of some good during-the-week group rides that some local cycling teams/clubs might be happening. Also, if there's a park or particular course where cyclists tend to gather. Here in Washington, DC, there's a spot (Hains Point) where people show up on a regular basis for unorganized friendly competition - something like that would be perfect to start or finish off my day while in Denver. Please post any ideas, and thanks.
