Makybe Diva's first foal Rockstardom is on track to make his race debut before the end of the month.

Trainer Danny O'Brien said the three-year-old Galileo colt would have his first start in a country maiden in the next two weeks but the venue had yet to be decided.

"It just depends on the tracks," O'Brien said.

"If we can't get a reasonable surface at Bendigo or Ballarat he might have to run in a maiden over 1300 metres on the synthetic at Geelong."

Rockstardom is currently stabled at O'Brien's Barwon Heads racing complex just outside Geelong and last Wednesday impressed the stable when he led all the way in a 1200-metre jump out on the new Geelong track.

O'Brien said the colt, who cost $1.5 million at the 2009 Australian Easter Yearling Sale and is part-owned by breeder Tony Santic, would be aimed at the Victoria Derby (2500m) at Flemington on October 30 .

"We bought him bought him to run a mile and half and the first mile and half race is the Derby," O'Brien said.

He said Rockstardom had been a progressive horse but his racing career had been deliberately put on hold until he turned three.

"Naturally we were never going to run him at two but he came in to the stable two or three times and in his jump outs he showed enough to please us.

"He has been back in work three months and we took him to Geelong for a trial last Wednesday and he jumped to the front and won comfortably enough."

O'Brien has yet to finalise a path to the Derby but is mindful that most three-year-olds that start out on the journey never make it to the classic.

"We will give him his chance to get there," O'Brien said.

"Historically it is a bit of an ask for them (three-year-olds) but if he's not ready for that pressure then we will just give ourselves a platform for the autumn with him."

Three-time Melbourne Cup winner Makybe Diva has been at stud since 2006 and she has had three foals.

Her second foal, a Fusaichi Pegasus filly, realised $1.2 million at this year's Australian Easter Sale while her third foal is a yearling colt by Encosta De Lago.

Her fourth foal by More Than Ready is due this month and she will then be covered by Darley's glamour sire Lonhro.
