The Calabasas Hidden Stairs has 375 steps. The 110 flights of the Twin Towers are equivalent to 2,200 steps, roughly going up the Calabasas stairway six times.
How a Stair Climb Works
- The distance: 110 flights, matching the height of the Twin Towers — commonly translated to roughly 2,200 steps, repeated laps of a stadium or arena staircase, or the equivalent in an office tower.
- The badge: Each climber is given the name and photograph of one of the fallen — firefighters, and at many events, police officers, Port Authority officers, and military personnel as well — to symbolically complete that person's journey.
- The bell: At many events, climbers ring a fire bell at the equivalent of the 78th floor — the highest floor firefighters are known to have reached on 9/11 — in honor of the person on their badge.
- Gear: Some climbers wear full bunker gear or a weighted vest to replicate the physical demand FDNY firefighters faced; this is typically encouraged but optional, and it is not a timed race.
- Who can join: Policies vary by event — some are open only to first responders, military, and their families, while many others (like most community stadium climbs) welcome any member of the public as a climber, volunteer, or spectator.
History of the 9/11 Stair Climb
The first stair climb held to support the mission of the National Fallen Firefighters Foundation was held on September 11, 2005. when five Colorado firefighters convened at a high-rise building in downtown Denver to climb 110 flights of stairs in memory of their FDNY brothers who were killed in the terrorist attacks of 9/11. The following year, twelve firefighters participated, representing four fire departments from the metro Denver area. Each subsequent years, attendance grew, until it was capped at 343 participants in 2008. 9/11 Memorial Stair Climbs - National Fallen Firefighters Foundation
Twenty-five years after the attacks of September 11, 2001, the National Fallen Firefighters Foundation launched #ForThe343, a nationwide movement inviting every American to honor the 343 firefighters who gave their lives that day — and every firefighter who has made the ultimate sacrifice since — through one shared act of remembrance.
