Last year he gave the horse that eye-catching prep run at Caulfield after he won the Prix Kergorlay at Deauville in France, while this year his campaign has been centred on the Melbourne Cup and nothing else.
The son of top-class 2400-metre horse Duke of Marmalade (a multiple group 1 winner for Coolmore) has been maintaining fitness at Werribee and will go into the Cup on Tuesday without a lead-up run.
Opinions are divided as to the efficacy of such a tactic. Several horses have run well or even won the Cup first up, although others have performed much better after the benefit of a run in Australian conditions.
''We have always felt that he is a horse that runs best fresh. He might lack that edge of fitness, so the trade-off is freshness and wellbeing against maybe that little bit of fitness.
Marmelo would not be suited if the ground is firm. This year he has had four starts in Europe, three of them in France, where the ground often is softer than in England. That was the case particularly this year where the UK enjoyed an unusually hot summer.
It hasn't all been plain sailing in France at the newly re-opened Longchamp track as the racing surface has, says Morrison, left something to be desired.
''The ground at Longchamp has been pretty ropey. Thats why they abandoned last week's meeting there. I don't think it helps running on that rough ground too much.
