This week's Winning Post is now available online here.

The purists' day has arrived, and the biggest Australian racing crowd of the year will be on course at Flemington for Victoria Derby day.

As always on this day, the three-year-olds take centre stage, not only in the derby itself but in the Group 1 Coolmore Stud Stakes for the sprinters.

The Anthony Cummings-trained El Castello will be highly fancied in the derby following his impressive Spring Champion win.

In the other Group 1, the miler mares match motors in the Empire Rose.

The day's richest race, however, is at Rosehill, where the cream of our four-year-old sprinter/milers battle for $10 million in the Golden Eagle. Other highlights include the $3 million Russell Balding Stakes, the $750,000 Rosehill Gold Cup and the $500,000 Four Pillars Midway for provincial horses and smaller city stables.

Meanwhile the Perth carnival continues to ramp up with the Prince of Wales and the Asian Beau.

Sunday sees cup meetings at Mornington (Peninsula Cup), Mortlake and Goulburn, and we've goot full form guides for all three.

Our form coverage kicks off on Friday with a full form guide for The Valley (plus 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, Rosehill in NSW, Morphettville in SA, Eagle Farm in Brisbane and Ascot in Perth.

Winning Post carries full-colour liftout guides for all those meetings plus Traralgon (Vic/SA/Tas 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 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.

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 6, 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 $6 and is available Thursday afternoon online ($5), the crack of dawn Friday in shops.
