Derby Down is a local celebration of the Kentucky Derby and is hosted by the La Feliz Guild - a fundraising arm of Valley Children's.
This year almost 1,000 people gathered at the Fresno Fairgrounds to watch the races and spend money for a good cause.
"You notice very dapper men and just gorgeous women in these fabulous costumes, you want to say it's a costume," Erika Hoppe with La Feliz Guild said. "And we get in the spirit of it let's do the derby for Children's Hospital."
Action News Anchor Warren Armstrong emceed the event.
