This Saturday, Australian racing delivers one of the great days on the world calendar. Two cities. Group 1 giants. One unmissable afternoon.

At Randwick, the time-honoured Epsom Handicap headlines a blockbuster card. For 160 years, this Group 1 mile has made careers and crowned champions. Super Impose won it in 1990 and '91, Desert War claimed back-to-back victories in 2004 and '05, while the great Winx took it in 2015, and Autumn Glow lifted the trophy last year. Over the famous Randwick Mile, with $1.5 million on the line, this year promises to write another chapter.

The depth of the card is breathtaking as the Group 1 Flight Stakes puts the best three-year-old fillies on display, the historic Metropolitan Handicap adds staying class. The Group 2 Premier Stakes over 1200m, worth $1 million, will send shockwaves toward The Everest, now just weeks away. And this season's crop of two-year-olds make their first public race appearance, with Golden Slipper dreams on the line.

Most days, that would be more than enough. Not this one.

In Melbourne, Turnbull Stakes Day ignites at Flemington. Its honour roll reads like a hall of fame: Ajax, Leilani, Dulcify, Vo Rogue, Super Impose, Sunline, Winx, Verry Elleegant, Via Sistina and, last year, Sir Delius. A Group 1 over 2000m that stands toe to toe with the best in the world.

And the drama doesn't stop there. The Bart Cummings Stakes offers a golden ticket to the Melbourne Cup, in a race named for the greatest Cup trainer of all time. Bart won the Cup an extraordinary 12 times, and fittingly, the winner will take its place in the field on the first Tuesday of November.

The Australian Racing Carnival is in top gear. The road to The Everest and the Melbourne Cup steps up a notch here. Two cities. Countless stars. One massive Saturday. Watch it all, live, in your home of Australian racing.
