Rick Hore-Lacy admits he doesn’t know whether Chase The Rainbow will run a strong 2400m but he’s more than willing to find out.

The future stallion prospect has returned to work after injury cut short last year’s spring campaign and will be aimed at the Caulfield Cup (2400m).

Chase The Rainbow produced a dominant 3 1/2 length win in his only 2012 start and his trainer is confident he can find his best this spring.

“I’m going to enter him for the Caulfield Cup,” Hore-Lacy told Racing Victoria.

“He’s sound and injury free and I’m very happy with him.”

Yet to be tested over more than 1600m, Hore-Lacy said his racing style is reason to be confident he can step up in distance.

“He certainly ran the mile out strongly at Moonee Valley as a three-year-old and he doesn’t pull which are both good signs for a stayer,” Hore-Lacy said.

A rising five-year-old, the grey son of Dash For Cash has had an injury-plagued career, restricting him to just seven starts.

From that he has chalked up four victories including a dominant performance in the Group 2 Stutt Stakes at Moonee Valley in 2011.

Hore-Lacy was aiming Chase The Rainbow at the Caulfield Cup last year before injury intervened.

The experienced trainer has never won the race but has tasted plenty of success at the top level, with Redoute’s Choice, Canny Lad and Spartacus among the multiple Group 1 winners he has prepared.
