Richard Pestes of PezCycling News published an article about his experience riding the Time Trial course at the Tour of Germany (DeutscheTour) through a program called Giant Tour. Giant Bicycles apparently has a huge presence in Germany, in part because it is the bicycle sponsor of the T-Mobile Professional Cycling Team. Pestes said:

The coolest part of the Giant Tour is that regular Joe’s can sign up to ride a stage race, on closed roads – the same routes used by the DeutschTour - with police escorts, electronic timing, hot showers, hot food, roadside fans, and the feel of what it’s like to be a real pro racer. The stages run on the second half of each day’s DeutschTour route, and if you’re too slow – there’s a broom wagon to sweep you up.

Media covering the DeutscheTour who were up for a challenge got to ride team-issue bikes. Pestes' was the same Time Trial bike as the T-Mobile team raced in the 2004 Tour de France.

Check out the article. It has a lot of good photos of the bike he rode. I'm jealous.
