20th Anniversary Flagstaff 911 Tower Challenge 2021

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.

Together we vow to Never Forget.

For more information, please visit the 911 Tower Challenge Foundation website.

At this time we are on track to hold the 9/11 Tower Challenge at the Tucson Community Center (TCC) Arena. We have also added a virtual registration for those who either cannot attend or who do not want to attend in-person. See below for additional information about this option.

We are monitoring the situation and working with the venue and our local elected officials to ensure the safest situation for everyone and will implement any required minimum distances and protocols required by the venue.

When you register to attend virtually, you will receive all of the t-shirt, swag bags, coins and badges as those who attend in-person. Virtual attendees do not complete the challenge at the venue but instead find a location (gym stair-stepper, running/walking, high school stadium steps, etc.) to complete the challenge on their own. This is a great option for those who don’t live in Arizona but want to participate.

The opening ceremonies begin promptly at 0700 so please ensure to allow enough time to park and check in prior to that time. We recommend arriving 30 minutes early.

Early registration ends August 6 with a guaranteed t-shirt size of choice and we are also limiting the number of in-person attendees, so it's critical to sign up early to ensure you get a spot.

Having an early registration allows us to guarantee t-shirt sizes and ensure they arrive in time for packet pickup (or mail-out) prior to the event. After early registration has ended on August 6, the entry fee will rise, and t-shirt sizes will no longer be guaranteed.

All registrations will end August 31 or when event capacity is reached. If available, late registration will open September 1 and end September 10, but packets will not be mailed until after the event.

Packets will be mailed by September 1, except late registrants (if any) will receive their packets after the event. All participants will receive a swag bag with a commemorative badge and t-shirt, along with other goodies from the sponsors. No packet pickup will take place.

This year, all packets will be mailed (shipping is included in the registration). We will not hold packet pickups this year.

Only if we have not reached event capacity! Once capacity is reached, we will be unable to accommodate day-of registrants. Please be aware that for day-of registrants, a t-shirt is not guaranteed, and you may miss the beginning of the event. We highly recommend registering for the event prior to its start time.

Children must be 16 & older to climb the stairs, and may not be carried on the stairs during the event, however they may participate in the concourse walk. Child care is not provided, however each location will have a designated area for children with their guardians.

All non-participants must be supporting a registered individual. To reserve a spot, select the “Non-Participant Attendee” free registration and fill out the information. As a requirement of attending, you’ll need to put in the name of the person that is being supported and we will check to ensure that person is registered.

Park in lot P66 on the South Side of the Skydome on San Francisco Street and East Pine Knoll Drive. No parking pass is needed to park!

Comfortable clothing, running shoes/sneakers, and the badge you received in your registration bag (this gains you entry to the event).

Thank you SO much for your service! You are the reason why we hold this event. We don’t have a general discount because the majority of attendees are first responders of some type - and the proceeds are fed directly back into your community via the beneficiaries.

What we do instead is give a discount to all ROTC Cadets! If you fall into this category, please get with your leadership for your code. If they don’t have the code, please have them email us directly.
