The only sure bet on the Melbourne Cup is that Lloyd Williams, or anyone else for that matter, won't be taking on “crazy owner” Dr Marwan Koukash's promise to accept the trophy in his G-string.
Mr Williams is out to add a seventh Cup to his already record haul.
But there are many others hoping to get in his way such as the ruler of Dubai and head of the world's biggest racing operation Sheikh Mohammed, who has been trying to win the Cup for 30 years.
And then there's Dr Koukash, the Palestinian refugee turned British billionaire who is adamant his horse Magic Circle will win what he classes as the best race in the world.
He is equally determined to celebrate by stripping down to his G-string, despite the Victoria Racing Club saying it would be a shame if the enthusiastic owner had to miss the presentation due to a ‘wardrobe malfunction'.
“When we win the Cup, shortly after 3 o'clock Flemington will see something they have never seen before and are unlikely to ever see again,” Dr Koukash declared.
“They're going to have a crazy owner wearing nothing but this, a tie and socks,” he said, showing off a bright pink G-string.
“That crazy owner is me.”
Irish trainer Aidan O'Brien, who had to settle for second in last year's Cup behind his son Joseph, trains Rostropovich as well as both of the Williams family's runners Yucatan and The Cliffsofmoher.
Australia's leading Group One trainer Chris Waller has three contenders in Finche, Youngstar and Who Shot Thebarman.
“It's fantastic, it's what we race horses for.
“We enjoy every minute of it.”
Craig Williams still needs a Melbourne Cup win to join a select group of jockeys to have won a Melbourne Cup, Caulfield Cup, Cox Plate and Golden Slipper.
The Melbourne Cup is the race that “drives us all”, the Youngstar jockey said.
“Not only is it the race that stops our nation, it's also now the race that's targeted around the world.
“If I could win it, it's going to be the greatest race on earth.”
Dwayne Dunn, who will ride Sir Charles Road on Tuesday, also dreams of winning a Melbourne Cup.
“You get out of bed very early and spend a lot of time on the back of horses.
“This is the one goal, we want to tick this box and win our grand final.”
More than 90,000 people are expected at Flemington and they will need to be armed with umbrellas.
The Bureau of Meteorology has predicted a rainy morning, easing to a few showers by race time, with a maximum of 20C.
