1,000 people from across the country and around the world raced up 180 flights of stairs to the 90th floor of the new One World Trade Center building for the first-ever World Trade Center Stair Climb.

For the first responders and family members, it was a moment to take back the space where their loved ones lost their lives. For elite racers, it was a chance to take on an iconic American symbol.

Arthel Neville reported on "America's News Headquarters" that the race was organized by two foundations formed after 9/11 and is raising money to build homes for wounded veterans and for the education of orphaned children whose parents died in combat.

Retired Army Sgt. Bryan Dilberian, who lost his left arm and both legs in an IED explosion in Afghanistan in 2011, was determined to finish the race despite having two prosthetic legs.

"When I was deployed to the 10th Mountain Division, everyone always said, 'Climb to glory,'" Dilberian said. "So now, 'climb to glory' has a whole new meaning to me. And I’m going to overcome these stairs at the World Trade Center."

For Michael Burke, brother of Captain Billy Burke, who died on 9/11, the race was a chance to finish the climb his brother never did.

"It was a tough climb, I’m telling you," Burke said. "But it was great. It was a great experience for a great cause."
