Universities and sports organizations across the United States held memorial stair climbs on Friday, commemorating the 25th anniversary of the September 11, 2001 terrorist attacks. These events honored the victims and the first responders who lost their lives.

Participants climbed the equivalent of 110 stories, mirroring the height of the World Trade Center's Twin Towers, to pay tribute to the 343 firefighters and other emergency personnel who perished on 9/11. The stair climbs took place in local stadiums and other prominent venues nationwide.

These commemorations serve as a reminder of the unity and resilience displayed by Americans in the aftermath of the attacks. In an era where sports and national discourse can sometimes be divisive, these events highlight a collective remembrance and a recognition of the sacrifices made for freedom.

The 9/11 terrorist attacks, which involved hijacked airplanes striking the World Trade Center in New York City and the Pentagon, instilled fear and confusion across the nation. Sports played a significant role in the healing process, unifying and inspiring Americans. Decades later, these traditions continue, with teams, leagues, and universities actively participating in remembrance.

Al Leiter, a former Mets pitcher, shared his personal account of the events and their impact. The widespread participation in stair climbs underscores a commitment to remembering the bravery of first responders and the ultimate cost of freedom. The events concluded with well wishes for the first responders and participants who honored the memory of those lost.
