Hundreds of walkers laced up their sneakers to walk through Brooklyn and Manhattan from Saturday night to Sunday morning to raise awareness and money for suicide prevention.

The 18-mile Out Of The Darkness Overnight Walk wrapped up early Sunday, nearly 10 hours after walkers stepped off from Cadman Plaza in Brooklyn.

They crossed the Brooklyn Bridge into Lower Manhattan, then made their way along the West Side before heading back to their starting point.

Some walkers had very personal reasons for taking part.

"I actually saw the billboard for the Out Of The Darkness Overnight Walk on a train heading to Newark and the day I saw it was the five year anniversary of my suicide attempt. So I took it as a sign that I really needed to participate," said one walker.

"It's important to me to break that stigma and end that silence," said another.

"I think something can be done about suicide and I want to be part of what it takes," said a third.

The event was organized by the American Foundation for Suicide Prevention. All of the money raised will go towards research, advocacy, and awareness programs.
