911 Tower Challenge Climb

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.
