This week's Winning Post will be available online here from 3pm AEST Thursday.

One of the great days on the Australian racing calendar is upon us, with Randwick's traditional spring showpiece in Sydney and a quality-packed Turnbull Stakes day in Melbourne.

The headline act at Flemington will again be reigning horse of the year Via Sistina, who will be out to bounce back to winning form in the Turnbull after her third in a slowly run Makybe Diva Stakes.

There's a triple Group 1 card at Randwick, with the milers duking it out in the Epsom, the stayers going toe to toe in the Metropolitan and the fillies matching motors in the Flight.

Our form coverage kicks off on Friday with a full form guide for The Valley (and Launceston in the Tassie edition), plus fields, colours and tips for the other Friday TAB meetings.

The metro racing this Saturday is at Flemington in Melbourne, Randwick in Sydney, Morphettville in Adelaide, Doomben in Brisbane and Kalgoorlie in WA.

Winning Post carries full-colour liftout guides for all those meetings plus Murtoa (Vic/SA edition), Newcastle (NSW edition) and Gold Coast (Qld edition), as well as fields, tips, ratings and/or colours for other TAB Saturday cards.

On Sunday there's plenty of punting to do in the countdown to the NRL grand final and we've got liftout formguides for three more TAB meetings as well as fields, ratings, tips and colours for a stack more Sunday and Monday programs.

Don't forget Winning Post now carries trackwork reports for all four Melbourne training tracks, all three in Sydney, Morphettville in Adelaide and a general Brisbane report.
