Pierce Manufacturing and the Green Bay Metro Fire Department have announced that registration is now open for the 14th annual 9/11 Memorial Stair Climb at Lambeau Field in Green Bay, Wisconsin.

The event will take place on Saturday, September 12 marking 25 years since 9/11.

Event honours fallen firefighters

Open to all participants wishing to honour the 343 firefighters who lost their lives on 9/11, all proceeds from the event will benefit the National Fallen Firefighters Foundation (NFFF).

Organisers are encouraging early registration through the Pierce Manufacturing website.

In 2025, more than 2,000 participants including firefighters, families, supporters and community members attended the event. Organisers now aim to make the 2026 memorial climb the largest in the event’s history.

Symbolic stair climb challenge

Participants will climb the equivalent of 110 stories, matching the height of the World Trade Center towers, using the steps at Lambeau Field.

Each climber carries an honour badge featuring the name and photograph of one of the fallen firefighters.

At the equivalent of the 78th floor, the highest point reached by firefighters during the attacks, participants ring a fire bell in tribute.

Event details confirmed

Registration costs are $35 through July 11, $40 between July 12 and August 15, and $45 from August 16 until event day.

The opening ceremony begins at 9am and includes the Presentation of the Colors, National Anthem, prayers and remarks from the NFFF before climbers begin the memorial ascent.
