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

Two of the great races on the Australian calendar go head to head this week, one of them 145 years old and the other just seven years young.

The local, imported and overseas stayers do battle in the Caulfield Cup, while the best sprinters in the land duke it out in the $20 million Everest at Randwick, where enigmatic ex-Kiwi I Wish I Win is sure to be among the main fancies.

The King Charles III Stakes for the milers and the Kosciuszko for the country sprinters add intrigue to the Randwick card, while the Sportsbet Classic for the drby-bound three-year-olds, the Thousand Guineas Prelude for the fillies and the Caulfield Sprint are on the undercard at the Heath.

In Adelaide, more Victoria Derby contenders will be going around in the Hill Smith Stakes at Morphettville.

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

The metro racing this Saturday is at Caulfield in Melbourne, Randwick in Sydney, Morphettville in Adelaide, Eagle Farm in Brisbane and Ascot in Perth.

Winning Post carries full-colour liftout guides for all those meetings plus Bendigo (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 three more TAB meetings inlcuding Horsham Cup day 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.
