If it was blinking, shining or glowing - it was in here Saturday night where colorfully lit up runners filled Belmont Plateau all for fun and charity.
"Listen baby we are in Philadelphia, red, white and blue - we gotta go big come on," said Marc Garabedian.
Thousands suited up using glow sticks, LEDs and whatever else they could find to make them stand out for the Electric Run.
It was a nighttime 5k run and walk through an electric wonderland course.
It's been done in several other major cities but it was the first for Philadelphia with a portion of the proceeds going to 'Variety,' a children's charity.
"Oh this is a fantastic event. We're raising awareness, we're raising money got a good night out of it," said John Forti.

Despite all the wild weather, authorities say fortunately there have been no related injuries.
