Trainer David Vandyke is not convinced Arabian Gold is a genuine stayer despite the filly's dominant win in The Roses at Doomben on Saturday.

Arabian Gold ($2.10 fav) defied the pattern of the day when she covered ground on the home turn before sweeping past her rivals in the straight to win by 1-1/4 lengths from Tinto ($13) with Tornado Miss ($61) a similar margin away third.

Vandyke admits the 2400 metres of the Group One Queensland Oaks (2400m) at Eagle Farm on May 31 is a concern for Arabian Gold.

"It's definitely a risk and I want to see how she pulls up before we see if she runs in the Oaks," Vandyke said.

"I'm mindful this is the fourth carnival in a row that she's competed at and she's done a great job until now."

Vandyke was confident of victory when jockey Blake Shinn had Arabian Gold travelling comfortably midfield before allowing her to stride foward approaching the home turn.

"It's a relief to win because, on paper, I didn't think she could be beaten today," he said.

"I was confident she had the ability to outsprint her rivals because she has a very economical action and keeps herself balanced.

"Blake allowed her to track through her gears and she let down beautifully."

Shinn said Arabian Gold always had her rivals covered but echoed Vandyke's assessment of the filly's staying ability.

"I think 2000 metres is her pet distance but she's a filly of high quality and often when they're racing their own age group class prevails," he said.

Tim Bell, who rode Tinto, believes the filly will be highly competitive in the Oaks.

"She'll relish another 400 metres and even though Arabian Gold won well, my filly was taking ground off her at the finish," he said.
