This is the 13th time a horse has won the Triple Crown.
He'll be wearing red silks with gold stars for the China Horse Club.
WinStar picked up the future Kentucky Derby and Preakness winner as a yearling in 2016.
The horse went for his final gallop at Churchill Downs on Tuesday.
She will take home about the same amount of money as Justify's owners.
Lots of people come back to Churchill Downs year after year for the Derby festivities.
The Run for the Roses draws people from all over who want to get in on the fun!
