The Helene Vitality team is going into today's Group One A$2.1 million Caulfield Cup in Melbourne underrated but not under-confident despite the task faced by the David Hayes-trained stayer in one of Australia's greatest events. The scratching through injury of topline mare Magical Miss has brought Helene Vitality in to barrier 13 and reduced by one the depth of opposition, but the gelding is still listed in ante-post betting as a 20-1 prospect for the 2,400-metre race. Helene Vitality has pleased in his lead-up work, though the ever-optimistic Hayes admits there will be a luck element required. 'We'll need a good ride by Dwayne Dunn, but at least I know the horse is going well and is very strong at the trip,' Hayes said yesterday. Tony McEvoy, Hayes' trainer for the Lindsay Park operation, is hoping for victory with 3.5-1 favourite Fields Of Omagh, but has also been the caretaker of Helene Vitality for the stayer's build-up to next month's Melbourne Cup, his main target. Earlier in the week, McEvoy told Hayes he thought Helene Vitality was short of fitness and might have to miss the Caulfield Cup. When a surprised Hayes asked him why, McEvoy said, tongue in cheek, 'because I haven't been working him'. McEvoy quickly added that he was joking and that his Hong Kong rival was actually in good form and a possible threat to his runner. Dunn said there was something special about 'going home' to ride in a race that meant so much to Australians, especially after he had missed the ride through suspension when Helene Vitality finished second in the Dubai Sheema Classic. 'Missing Dubai was disappointing but it means more to ride him in Melbourne,' Dunn said. 'One thing about Hong Kong is that you get the chance to be involved in these big international races. I know I couldn't do it from Australia, especially Adelaide. I've got six other rides on the day, too, and there's no doubt you get more respect coming back from Hong Kong.' Dunn is yet to win a Group One on home soil and has had only one previous Caulfield Cup ride, partnering Skybeau to 13th in 1997, when Might And Power spreadeagled the field by 7.5 lengths in record time. 'They can run along in the Caulfield Cup and whether that speed comes against this horse, we will see,' Dunn said. 'But we know he is world class at 2,400 metres - Dubai proved that. And unlike Dubai, the Caulfield Cup is a handicap so he must be a chance on good going.' While the Melbourne weather lies somewhere between the Triple Trio and the Mark Six for predictability, the forecast is not all bad, with warnings of isolated showers but mainly fine weather. Hong Kong racing fans will be able to watch the Caulfield Cup on the Diamond Vision screens and closed-circuit televisions at both Sha Tin and Happy Valley racecourses tomorrow at about 12.35pm before the first race is run at Sha Tin. ATV will show the race tonight on the Home Channel at 11.55pm during the Horse Racing Preview programme and on the World Channel at 11.15pm during the Racing To Win programme. Cable TV viewers can watch the race on Channel 82 tonight at 8pm during the Racing To Win programme and on Channel 18 at 12.15pm tomorrow during the Trackside programme.
