On Monday, December 10, Splash and Chicago magazine hosted dozens of climbers at Brooklyn Boulders for the latest iteration of our fitness event, Fit Society. The idea: Members sign up over the course of the year to get on an email list, where we later blast out a link to buy tickets for a workout class at a secret location. On the day before the class, members get an email telling them where the action's at — in this case, Brooklyn Boulders in West Loop. At the event, guests took an intro to climbing class then indulged in a healthy happy hour including Protein Bar wraps, sparkling water from Polar Beverage, and Boxed Water. Michelob Ultra doled out beer samples and winter swag, while Mario Tricoci gave 5-minute manicures, hand scrubs, and massages. Peep the photos below.
