Black Caviar's workload will be stepped up over the next five weeks as the champion prepares for a return to the racetrack.
The mare is at Peter Clarke's property in country Victoria, her home away from home throughout her career.
Clarke made his name with the invention of the water walker for horses which raises their fitness levels without the strain of galloping on hard tracks.
Trainer Peter Moody said he expected Black Caviar to return to his Caulfield stable in January to prepare for the Group 1 Lightning Stakes in February which now bears her name.
However, he also said he would not hesitate to retire her if he felt she did not come up to expectations.
"She's full bore from tomorrow towards the Lightning," Moody told Melbourne's radio RSN on Sunday."We're very happy with her but obviously extremely conscious of the situation we are in with her that we don't want to see her beaten now.
