Participants climb 94 flights of stairs for Hustle Chicago Hundreds of Chicagoans got their blood flowing for a good cause Sunday morning. They took part in Hustle Chicago, formerly known as Hustle up the Hancock. The event was renamed because the iconic skyscraper at 875 N. Michigan Ave. where it takes place is not officially called the John Hancock Center anymore. In Hustle Chicago, each participant climbed 94 flights of stairs — 1,632 stairs in all.
