Participants gathered at the Gila River Arena in Glendale on Tuesday to take part in the third annual 911 Tower Challenge.

As they climbed the 2,071 steps - the same number of steps in each of the Twin Towers - participants carried the names of first responders who died on 9/11.

Photos of fallen 9/11 first responders were posted along the stairways in the arena

Those who were unable to climb due to age or injury walked the arena concourse.

The challenge helps raise funds to support 100 Club of Arizona, a local nonprofit that supports first responders and their families. So it's an amazing way to honor the legacy of those who sacrificed for the safety of others on 9/11. Money raised will also benefit the Fighter Country Foundation.
