The Championships get underway at Royal Randwick with a superstar cameo kicking things off.

Champion mare Winx will go out for an exhibition gallop at 11.50am, a week before her retirement race in the Queen Elizabeth Stakes on April 13.

The rest of the day is filled with a world-class field of racing including the $2.5-million TJ Smith Stakes.

Star sprinter Redzel is in the field, looking to increase his 15 and a half million dollars in career prize money.

After missing out on a share in Black Caviar due to his cancer treatment, Peter managed to snag a stake is the superstar gelding and has enjoyed every minute of it.

“No matter how crook I am, he makes me feel a million dollars. He is an amazing animal,” Peter tells Alan Jones.
