Thousands of firefighters and supporters will be racing up to the top of the Renaissance Center Sunday, to participate in the Fight for Air Climb. It's all to support the American Lung Association.
The climb starts at 10 a.m. Participants will climb up 71 flights of stairs -- while being timed. They can also take part in the half climb -- which is 40 floors and untimed.
Registration is full -- but for more information, or to donate, visit the American Lung Association's website.
