Light showers are forecast for Melbourne before the 150th Melbourne Cup.
So You Think is the race favourite with trainer Bart Cummings confident the four-year-old can deliver him his 13th Cup title.
"Definitely, I am very, very certain he has (the endurance), he's ready to go two miles or further, that's what I bought him for and that's what we aim to do tomorrow," Cummings told The 7.30 Report on ABC on Monday.
"He accepts the fact that he just settles in his stride and he'll go all day doing it, that's why I think he'll get the two mile no trouble."
Cummings said that ideally he would like to see So You Think in about 10th place 500m into the race, but he will leave it to jockey Steve Arnold.
"He knows what to do, I'll have a talk with him, we'll sort it out," he said.
Cummings, 85, was released from hospital on Sunday, after being admitted with a chest infection on Wednesday.
He said he will definitely be at Flemington on Tuesday and he also likes his other runner Precedence's chances.
"I'm ready for another win," he said.
The 2010 Melbourne Cup is being described as having the strongest field in more than a decade and Cummings says the wet condition of the track will suit the imported horses.
More than 60mm of rain fell on the track at Flemington on Sunday.
Cambridge-trained Harris Tweed is the second favourite on the New Zealand TAB.
