Admire Rakti's victory at Caulfield meant that his weight for the Melbourne Cup was increased to 58.5 kg, a weight higher than any winner of the race had carried since Think Big in 1975. Admire Rakti started 9/2 favourite, but weakened badly in the last 600 metres and finished last of the twenty-two runners. After the race, he collapsed and died from cardiac arrest after ventricular fibrillation.[1]
