Step Up to the Challenge and join us at the Fight For Air Climb. When you participate in a Fight For Air Climb, you are stepping up to make a positive impact in the lives of those affected by lung disease. Participants raise funds to support the mission of the American Lung Association while training to climb 48 floors, 1,062 step to the top of The First City Tower. Whether you are climbing alone or with friends and family, as a part of a healthy lifestyle or in honor of all those who are affected by lung disease, you will achieve a sense of personal accomplishment as you reach the top of the building and the height of your fundraising potential. Every step you take moves us forward in our fight for healthy lungs and clean air.
