Dermot Weld is eyeing the Irish St Leger ahead of a possible Melbourne Cup campaign for Galileo's Choice after his victory in the Challenge Stakes at Leopardstown.

The six-year-old was Grade One-placed over hurdles during the winter, but showed he still has plenty of ability on the level when landing the 14-furlong Listed event.

That was his first run on the flat since winning at Group Three on the track last September and Weld is now planning to raise his sights to Group One company.

"The Irish St Leger is the logical progression for him. He's going to have an entry in the Melbourne Cup and we'll see how we go along the way," he said.

"He'll probably have one more run before the Irish St Leger and we'll see how he gets on there, but he'll certainly be entered for the Melbourne Cup.

"It was a lovely performance by him, he had to get tired. Pat (Smullen, jockey) said he got tired about a furlong and a half down, but got a second wind and ran on nicely.

"He's the sort of horse I love to train - he's a fun horse, he's a right horse and he's a very adaptable horse."

Galileo's Choice remained a $51 Melbourne Cup chance on TAB Sportsbet's book despite the victory - and Weld's record as a two-time winner of Australia's greatest race.

"There's been no interest from punters since Galileo's Choice's win," TAB Sportsbet's media manager Glenn Munsie said. "It has been $51 since the market opened and there's only been $50 invested on the horse so far."
