The NASCAR Sprint Cup is coming to the Kentucky Speedway for the first time ever!
Racing starts Thursday.
But before getting to the race, the stars of the sport are coming to Louisville.
Some of the cars will be at Fourth Street Live, including David Ragan's car.
Ragan won the Coke Zero 400 at Daytona International Speedway this weekend.
He drives the UPS car.
While at Fourth Street, you also have the chance to win tickets to Saturday's race.
That event runs from 11:30 A.M. to 1 P.M.
Then later in the day, Driver Denny Hamlin joins FedEx and the Red Cross at the Portland Community Center.
They'll be teaching children about preparing for natural disasters from 2 P.M. until 3:30 P.M.
