The New York City Memorial Stair Climb sees 343 firefighters/emt's and 60 law enforcement personnel from around the world ascend the stairs of a skyscraper at ground zero every year in memory of the first responders killed on September 11th 2001. Each participant climbs in honor of one of the over 400 emergency responders killed that day. Climbers are also encouraged to honor any fallen first responders and military personnel worldwide. The event is foremost a memorial climb, however a 9/11 related beneficiary is chosen each year by the organizers. Climbers are encouraged to fundraise but are not required to. Climbers are also given the opportunity to be timed if they choose to race. The New York City Memorial Stair Climb is a 501c3 sanctioned event of the Association of Memorial Stair Climbs. It was founded by and continues to be organized by FDNY firefighters. All organizers are volunteer based and are 100% non-compensated.
