She is the fastest horse on earth and her trainer believes there isn't another alive that can beat her.
But as Black Caviar boarded a plane for England yesterday, Peter Moody warned she wouldn't take a single step on an English racecourse unless she came through the trip in perfect shape.
"If she doesn't travel well and I'm not 100 per cent happy with her, everyone will have a nice holiday in England and won't see her race," Moody said.
Black Caviar will attempt to win her 22nd race from as many starts in the Diamond Jubilee Stakes (1200m) at Royal Ascot on June 23 and Moody is supremely confident she will keep her unbeaten record intact.
"She's getting on the plane the fittest she's been in her career," he said.
Moody has devised a special programme under which Black Caviar did her most testing gallops at home at Caulfield, leaving her two weeks in England to recover from the flight.
"I don't want to have to train her for the next two weeks," Moody said.
In his efforts to have his champion mare ready for her appointment with the Queen at Royal Ascot, Moody has gone to extraordinary lengths.
As well as the celebrated compression suit she will wear on the flight, Moody has made it clear to Singapore Airlines that they have a special passenger on board and has sent her vet Peter Angus, his stable foreman Tony Haydon and exercise rider Paddy Bell on the flight with her.
Black Caviar modelled the suit at the stables of Moody, who said it was very much part of her preparation.
"We thought if it was good enough for Sally Pearson [Australian hurdler], it was good enough for Black Caviar. Nothing but the best for the best," Moody told the Herald Sun.
"This mare has always been quite susceptible to soft-tissue injuries and muscle tears and we thought it might aid her in that way.
"And the fact is she is going to be standing in a horse box for some 30 hours, and it seems to be the done thing with all sportspeople that they wear skins and tights to create blood flow when they're travelling."
The compression suit can be zipped and unzipped in about 30 seconds.
He also sent a load of her favourite feed to England ahead of her last week.
"Singapore Airlines have been terrific, they realise what cargo they're carrying and every effort has been made to keep the stopovers as brief as possible," he said.
Unlike regular passengers who can walk around the cabin, Black Caviar will have to stand in her crate for at least 30 hours, depending on the length of stopovers in Singapore and Sharjah.
By the time she gets to her English stables at Newmarket she is likely to have been in a plane or a truck for around 36 hours.
Moody said he would consider running Black Caviar in the July Cup (1200m) at Newmarket on July 14 should she come through the Ascot run in good order.
He also promised that a wet track would be no barrier to her starting at Royal Ascot.
In other news from Australia, a perfect barrier wasn't enough to convince Sydney trainer John O'Shea to declare Sea Siren a definite starter in the Stradbroke Handicap at Eagle Farm on Saturday.
Sea Siren drew ideally in barrier six for the 1400m group one feature and is now a clear-cut $4.20 favourite with TAB Sportsbet for Queensland's biggest race.
Two factors still concern O'Shea: "Her weight (55kg) and the track are my concerns. History is well against her probably more so in the Stradbroke than it was when she won the Doomben 10,000."
Eagle Farm was rated a slow (7) yesterday and a further upgrade to dead is likely but only if predicted rain tomorrow and Saturday fails to eventuate. Sea Siren became the first filly to win the Doomben 10,000 last month when she downed Queenslander Buffering.
O'Shea is leaving the final decision on whether she starts to her owner, Perth businessman Keith Biggs.
With a spring campaign ahead, possibly aimed at the Myer Classic, O'Shea is wary about overtaxing the filly who has started seven times for five wins and two placings.
Buffering, who produced a courageous performance to finish second after a setback in the Doomben 10,000, has blown to $7.50 after drawing barrier 18.
He will jump from 14 if the five emergencies, which include Pampelonne (13) and Mental (21), don't start.
Trainer Rob Heathcote tried his best to put a favourable spin on the draw but with his big weight of 58kg and some doubt about the 4-year-old handling 1400m, bookmakers are likely to risk Buffering further. AAP
