This challenge was really eye-opening for me! While I knew that the firefighters climbed many flights of stairs to save lives, actually climbing the amount of stairs made me realize just how difficult that must have been! This challenge was much harder than I anticipated it to be; I have gained SO much more respect for firefighters! By the time we made it to 110 floors, I was sweating and breathing heavy! I can’t imagine doing it in firefighting gear! I am so in awe of the bravery and dedication of those first responders, who risked their lives to save others on 9/11.
