The first Saturday in May means it’s time for the 151st Kentucky Derby, America’s longest continuously held sporting event.

Nineteen horses stampeding 1 1/4 miles around Churchill Downs isn’t just a race. It’s 150,000 fans jammed under the Twin Spires for a fashion show mixed with an all-day party that is heavy on traditions like mint juleps, singing “My Old Kentucky Home” and a garland of red roses draped on the winner.

When is the Derby post time?

6:57 p.m. Eastern on Saturday.

What’s the forecast?
