Proceeds from the 5K race are used for awareness, research and treatment of diseases like breast, ovarian and uterine cancer.
ABC7 is a proud sponsor of the event. Eyewitness News anchors Ellen Leyva and Michelle Tuzee kicked off opening ceremonies.
Tuzee's mother, Diane, is currently battling breast cancer. She gave advice to others with cancer.
"I just want to say there's always hope," she said. "I'm in between treatments at the moment and I'll be starting them again soon, and there's lots of hope. Just keep going."
Eyewitness News Morning Show anchors Leslie Sykes, Phillip Palmer, weathercaster Garth Kemp and traffic reporter Alysha Del Valle also joined in to honor those lost and celebrate all those survivors.
"It's so inspiring to see all these people, and it's energizing because all of the strides that have been made for women's cancers and it's because of everybody coming out here and bringing attention to cancer that they have been able to do this and put money towards breast cancer research and all that. It's wonderful," said Sykes.
Celebrities at the event included Halle Berry, Brandy, Bruce Willis, Nolan Gould of "Modern Family" and former "Dancing With The Stars" host Samantha Harris.
But perhaps the biggest stars at the race were the cancer survivors.
"Fight the fight, go with it, and you'll survive. Things are looking great," said one survivor, who celebrated 25 cancer-free years.
"It's just a thing of unity, everybody is out here, men, women children, and it's beautiful," said cancer survivor Jonai Watson.
The event has raised $70 million over the years.
"We're actually funding science that's really making the difference in saving the lives of women," said Cathy James of the Entertainment Industry Foundation.
