Giant Steps For 9/11: Former NFL Star George Martin Raises Over $3 Million With A Walk

NEW YORK (CBSNewYork) -- Five years ago, New York Giants great George Martin walked across America in support of the first responders of 9/11.

Through his foundation, "A Journey for 9/11," Martin has raised more than $3 million for medical care for rescue and recovery workers at New York-area hospitals.

His quest took 10 months and 27 pairs of shoes - and he isn't done walking yet. The former football player and his son joined The Couch with his son George Martin II.

"It wasn't easy, it was very difficult at first," Martin said. "When you've been in NFL training camp, you find out a way to get things done."

Martin walked from the George Washington Bridge to San Diego, Calif. to raise money and awareness. He set out to do 20 miles a day (at least).

But why?

"We unfortunately lost some very good friends in those tragic events," Martin said. "That hit very close to home."

His son lost a close childhood friend, and his co-worker lost a son.

"You look at how the area had supported the NY Giants and myself for so many years, I felt it was time to use my celebrity to give something back and do something in support of the real heroes."
