Dozens of people climbed the equivalent of 110 stories in a 9/11 memorial stair climb at Nissan Stadium.
On September 11, 2001 343 New York City firefighters suited up for their last call.
The 9/11 stair climb was created to honor their brave response at the Twin Towers. Each climber wore a picture of fallen firefighter.
The stair climb was part of the Firehouse Expo going on at the Music City Center.
