About the Event: Remembering those who made the ultimate sacrifice 25 years ago.
In honor of those who lost their lives on 9/11/2001, and in continued honor of our first responders and military who protect us from foreign and domestic threats, we gather to pay our respects at the annual 911 Tower Challenge.
The World Trade Center's Twin Towers each consisted of 110 floors and 2071 steps, and each year thousands of people across Arizona walk, climb and run the stairs to remember. Firefighters in full gear, Police, Military and Bomb Squad personnel march steadily alongside civilians of varying ages, abilities and backgrounds.
Photographs of our fallen heroes line the stairs, and participants pause briefly to read the names in recognition of the sacrifice each made while in the service of others. This powerful morning will reconnect you to the kindness, strength and bravery exhibited on that dark day.
