Here’s some of what you may need to know – but no guarantees that it’s helpful – ahead of the big one on Tuesday. 

Overall, the field includes nine runners trained out of Australia, and 10 of the 15 Australia-based horses are important. 

Experts are giving the lot of them some sort of chance, a genuinely rare thing for the massive field and not so often run 3200m distance. 

Set your clock to 4am if you’d like to see it live.
