The 100 Club of Arizona invites Valley residents to participate in the annual memorial 9/11 Tower Challenge at Desert Diamond Arena in Glendale.

The event, on Saturday, Sept. 7, is open to the public and all active, reserve and retired members of fire service, law enforcement, first responders and military communities. The Tower Challenge will recognize those who lost their lives on 9/11 by participants climbing 2,071 of the arena’s steps, the same amount of steps that were in each of the Twin Towers.

Registration is open at 100club.org/event. All proceeds raised will benefit the 100 Club of Arizona.

The morning of Sept. 11, 2001, 2,977 victims, including 343 firefighters, eight emergency medical technicians, and 72 law enforcement officers from a total of eight local, state and federal agencies were killed when terrorists crashed four hijacked planes into the World Trade Center Towers in New York City, the Pentagon in Arlington, Virginia, and a field near Shanksville, Pennsylvania.

Over the 20-plus years since the terror attacks of Sept. 11, the U.S. has lost more than 7,000 members of the military and another 53,000 wounded, in the Global War on Terrorism, according to the 100 Club of Arizona.
