Strapping on 75 pounds of gear, teams of firefighters will storm more than a thousand steps Sunday at the One Woodward building.
Featuring 250 first responders representing 50 different departments, those making the climb will feel the pain - but it's a climb they're well acquainted with.
"Climbing the stairs going back to 9/11. Every firefighter is passionate about climbing stairs in memory of those who've fallen. We lost brothers that day and we climb every day for them," said Lenny Pusdesris, of the Grosse Ile Fire Department. Every year, the American Lung Association puts on the Fight For Air Climb in many of the country's most iconic skyscrapers. The goal is to fundraise and support those with lung-related illnesses.
