Coniston Bluebird continues to prove a handful on the training track and trainer Bede Murray believes his assignment at Warwick Farm on Wednesday could be his last as a colt.

But Murray's plans to run him in the $2 million New Zealand Derby (2400m) in February will remain in place if he handles the jump up to 2100 metres in the Wentworthville Handicap.

Murray admitted after the three-year-old's last-start win at Rosehill on November 15 that Coniston Bluebird would have been gelded if he had lost the race.

"He can still be very headstrong in his work and because of that we might be forced to have him gelded after this race," Murray said ahead of Wednesday's race.

The decision to geld Coniston Bluebird won't be taken lightly with the colt having the same sire as Melbourne Cup winner Viewed, Scenic, who also produced Murray's 2001 AJC Australian Derby winner Universal Prince.

"We'll have a serious think about it after tomorrow, this is a very important race for him and the longest trip he's run and will give us a good guide for the New Zealand Derby," Murray said.

At his last outing, Coniston Bluebird rocketed home over 1500 metres and defeated Togha by a half-neck.

"I've had to step up in distance a bit too quickly with him and would liked to have had another step in between," Murray said.

Regular jockey Glyn Schofield sticks with Coniston Bluebird who has topweight of 59.5kg in the four-horse field.

"You can never be too confident and I would expect them to put a fair amount of pace on and really make him carry his weight but speed will suit him and provide a good test," Murray said.

Murray is also looking forward to seeing his colt Universal Gold go around in the Penrith Maiden (1400m).

He finished fourth at Goulburn on debut in August and Murray said he faced a tough challenge after drawing barrier 11 of 13 but was capable of running a bold race.

"Normally if I have a horse who I think is ready to win and they draw badly at Warwick Farm I won't run them but this horse could still overcome the draw, he's a nice type," Murray said.

Stablemate Guanahani, a filly by Exceed And Excel, is making her debut in the Randwick Betting Auditorium Maiden (1400m).

"She's also drawn badly (nine) but her work has been pleasing and she will run well," Murray said.

"She'll be much better for the experience and will be a lovely filly up to 1600 metres."

Lou's Princess is looking for consecutive Warwick Farm victories and her third straight win when she races in the Yagoona Handicap (1600m).

"Barrier three probably won her the race last week at Warwick Farm and now she faces a much tougher challenge from the widest gate (10) in the race," Murray said.

"But she's going well and with a bit of luck will be right in the race."
