A workout today will decide whether high-class mare Coburg starts in the Interdominions.
Trainer Mike Berger has been struggling to get the group one-winning mare back to her best since a luckless trip to Addington last month.
Coburg has been listless and struggling with the summer heat and Berger saysshe will need to produce her best in this morning's workout to be in the fields, which will be released at 3pm.
"She hasn't been herself the last few weeks," said Berger, who also has veteran Facta Non Verba in the series.
"She has a hard race in her second start at Addington and she is a mare who doesn't really enjoy the heat, as she showed when she went off her food in Sydney in November."
Coburg pleased Berger with a more energetic workout on Saturday and if she can repeat that today she will start on Friday.
"I am pretty sure she will be there because she is on the way up."
Coburg is rated a $60 chance for the series.
Facta Non Verba is a definite starter even though Berger rates his Interdominion campaign as "pie in the sky stuff".
The 10-year-old retired last season but was brought back into work because Berger believed he enjoyed being in the stable environment.
He enjoyed it so much he was soon back in racing trim and now faces the toughest test of his career.
"He is up against it at his age but I thought he went better at his second start back and he should improve throughout the series.
"I would have liked to have got one more lead-up race into him down here [Cambridge] on Friday."
