Since then his career has been dogged by injury and he has had only six more runs.
He hasn't been at a distance further than 1600m since the Derby 26 months ago.
Forster has taken things slowly with I'm Belucci who spends a lot of time working on the beach.
“He has had three runs this campaign and the main thing is he got through them without any problems,” Forster said.
“That is the main thing with him, making certain he is sound. He ran a terrific second two runs back and then the race wasn't run to suit him last time.
“You won[‘t see the best of him until he gets to 2000 metres or further.”
Forster said a lack of suitable races had forced her hand with I'm Belucci
“He is a Class One horse who has been Group One placed so it makes things hard
“I want to get him out to 2000 metres or further which really means running him well and truly out of his grade,” she said.
Forster is worried the false rail being in the 7.5 metres spot on Saturday could disadvantage a back marker like I'm Belucci but she is hoping for a solid pace.
