LOUISVILLE, Ky. (WDRB) -- They were fighting for air one step at a time.

Participants walked all 780 steps of Louisville's National City Tower on Saturday to raise money for the American Lung Association.

The event supports those who've had lung cancer.

Steve Lindsey, who had a double lung transplant, says he couldn't even walk across the street without an oxygen tank before the operation.

 "It's almost as if I owe this debt that I can never pay, but I have to try," he said. "So I'm doing everything that I can do to make the gift that I got, worthwhile."

More than 63 climb events across the country last year raised more than $8 million

This year's goal is $9 million.
