An estimated 30,000 people packed downtown Houston for the city's annual event.
"We've raised about two million dollars," said Justine Schulerud with the Race for the Cure. "Our goal every year is about three million, so we're getting there. The money goes to research, education and screening right here in the Houston area."
Some who came out are cancer survivors. Others are supporting friends and family. Still others came out to raise awareness of a disease that kills nearly half a million people every year.
"I'm a new survivor," said participant Diandra Domino. "In fact, I'm still going through therapy and treatments, but I'm here to give my support and pass the word so everyone can be aware of breast cancer."
"We want to be future doctors and we want to help the world so we figured we'd start out here," said participant Brittany Aleman.
Arthur Fano came out to honor of his mom's battle with cancer.
"I'm very proud that she survived it," he said. "I'm just proud of her."
"It's a hard fight and if you can beat this you can do anything," said survivor Carolyn Leeds.
It's a promise that a community working together can make a difference, one step at a time.
