It's the biggest weekend in Australian sport, and a massive one in racing, with Group 1 action across three days.

And Winning Post has got it all covered, kicking off with the Moir Stakes meeting that opens the Valley night season on Friday night.

The Moir itself sees the return of Golden Slipper winner She Will Reign, while a strong support card includes the Stutt Stakes, the Stocks Stakes and the JRA Cup.

Randwick takes centre stage on AFL Grand Final day for a three-pronged Group 1 card. The Epsom, the Metrop and the Flight are the headline acts.

On Sunday there's plenty of quality racing to keep you entertained in the lead-up to the NRL decider, led by the Underwood and the Rupert Clarke at Caulfield.

Our form coverage kicks off on Friday with full form guides for Benalla Cup day, Moruya's Showcase day and the Valley night action plus fields, colours and selections for Rockhampton and Dubbo.

The metro racing this Saturday is at Mornington in Victoria, Randwick  in Sydney, Morphettville in Adelaide, the Sunshine Coast in Queensland and Belmont in Perth.

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

On Sunday we've got liftout formguides for four more TAB meetings including Caulfield's dual Group 1 day plus 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.

Away from the form, we've got news columns from Queensland, NSW, six Victorian districts, SA and Tasmania.

Our readers have their say on page 4, while further back in the book Shane Templeton reminisces, Paul Richards presents his unique take on the sport, Tony Kneebone brings you his Snippets column and Number Cruncher delivers the stats that matter.

Winning Post costs $5 and is available Thursday afternoon in selected Melbourne newsagents, the crack of dawn Friday elsewhere.
