Twenty-five years after September 11, 2001, Americans in nearly 250 communities are lacing up and climbing stairs to honor the firefighters who never came home. The National Fallen Firefighters Foundation (NFFF) launched #ForThe343 on August 11, inviting every American — not just firefighters — to take part ahead of the 25th anniversary of the attacks.
A Climb Built on Symbolism
The campaign builds on NFFF's long-running 9/11 Memorial Stair Climb tradition, in which participants climb 110 flights of stairs to mirror the height of the World Trade Center towers and the ascent FDNY firefighters made that morning while others were still coming down. This year, NFFF opened the challenge to anyone willing to climb even a single flight, post about it, and challenge someone else to do the same. More than 115 official stair climbs are planned across the country for the anniversary, with locations and sign-ups listed through NFFF's event finder.
It's a simple ask with a heavy purpose: honor the 343 FDNY firefighters killed on 9/11, along with every firefighter who has died in the line of duty since, one flight at a time.
More Than 100,000 Flights and Counting
By August 26, NFFF reported that participants had already climbed more than 100,000 flights of stairs nationwide. The list of climbers ranges from career and volunteer fire departments to everyday families, social media influencers, and even a former "Survivor" contestant. Fitness franchise Retro Fitness has signed on as a national partner, hosting 75 in-person stair-climb events at its locations on September 11 itself, giving people without a fire department climb nearby an easy way to join in.
That kind of grassroots reach is exactly what makes #ForThe343 stand out. It doesn't require race registration, travel, or specialized gear — just a staircase and the willingness to put in the work.
Why It Resonates With Our Community
For the veterans, service members, and first responders Operation WarriorFit exists to serve, #ForThe343 is a reminder that physical challenge and remembrance go hand in hand. A stair climb is scalable to anyone's fitness level, available almost anywhere, and rooted in the same mindset that carries our community through every 5K, obstacle course, and endurance race we help fund: show up, keep climbing, and do it for the people who can't.
If you're a veteran, active-duty service member, National Guard or Reserve member, or a current or retired first responder looking for your own next physical challenge, Operation WarriorFit can help cover the entry fee for a race that matters to you. See if you qualify and take the next step toward your own finish line.
