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

Hard to believe it, but the first Group 1 of the new season is upon us already.

The Chris Waller-trained Via Sistina carried the Yulong colours to victory in the 1400-metre weight-for-age showpiece last year and she'll have plenty of fans when she steps out again at Randwick on Saturday.

The Silver Shadow, Toy Show, Show County and Premier's Cup are the support acts at Randwick, while the Carlyon Stakes is the feature at The Valley.

At Morphettville it's Leon Macdonald Stakes day.

Our form coverage kicks off on Friday with a full form guide for Geelong, plus fields, colours and tips for the other Friday TAB meetings.

The metro racing this Saturday is at The Valley in Melbourne, Randwick in Sydney, Morphettville in SA, Eagle Farm in Brisbane and Belmont in Perth.

Winning Post carries full-colour liftout guides for all those meetings plus Wangaratta (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 we've got liftout formguides for four more TAB meetings (plus Hobart in the Tas edition) 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.
