As the last major lead-up event before the great fillies' classic itself, the group three Lowland Stakes over 2100m is arguably the best guide to what might happen in the New Zealand Oaks, two weeks later.
Often this one race at Hastings today is the moment of truth for those lucky enough to be associated with a promising filly - is their Oaks dream realistic, or is it just a bit beyond them?
That and so many other Oaks questions are answered in the Lowland, as fillies' class and stamina are put to the test.
Three Lowland winners in the past 10 years have gone on to win the Oaks, including Midnight Oil last year, and 2010 Lowland runner-up Keep The Peace went one better in the Wellington classic.
The Lowland is often won by a late-developing star filly who announces her arrival at elite level with an outstanding performance here before doing the same thing in the Oaks at Trentham.
