Thousand Guineas Prelude

Looking for early info on this year’s Thousand Guineas Prelude? The experts at Neds have put together everything you need to know before this year’s race.

Thousand Guineas Prelude, Caulfield

Run over 1,400 metres, the Thousand Guineas Prelude is a Group 2 race taking place at Caulfield Racecourse in mid to late September during the Melbourne Spring Racing Carnival. 

Formerly registered as the Tranquil Star Stakes in honour of former great mare and dual Cox Plate champion Tranquil Star (1942, 1944) the event has been run and won since 1983.

The race is run at set weights plus penalties and is open only to three-year-old fillies. Offering $300,000 in prize money as of 2021 the Thousand Guineas Prelude has been won by many great fillies over the years including Miss Finland (2006), Ortensia (2008) and Booker (2017).

It currently takes place on Sir Rupert Clarke Stakes Day alongside the colts’ and geldings’ equivalent, the Group 3 Caulfield Guineas Prelude (1400m).

By winning this race, fillies are exempt from the ballot for both the Thousand Guineas and the Caulfield Guineas but it is rare for a filly to take on the boys in the latter. 

Instead the Group 1 Thousand Guineas (1600m) is the likely target for the best out of the Prelude with Irish Lights (2009) the last to do the double.
