It’s been two years since we last published The 5280 50, a snapshot view of who’s who in Denver’s power structure. But in that short time, the Mile High City’s most powerful have played a game of Chutes and Ladders. We’ve got a new governor—and a new mayor. More than half of the list wasn’t on it last time. Aurora’s rising (or at least making a lot of noise). And Denver just might love bikes as much as it loves the Broncos.

Today, we’re giving you a sneak peak at our top 10. Each hour, we’ll release another name, so stay tuned. You might be surprised at who’s really running Denver.
