Trainer Ivan Allan will open Fairy King Prawn's season in the National Day Cup at Sha Tin on Monday as the dual Horse of the Year begins a campaign aimed at avenging last year's Hong Kong Mile defeat by Sunline. Allan finalised the plan only after putting Fairy King Prawn through his paces in yesterday's grass barrier trials at Sha Tin. The son of Danehill, who failed in his bid for back-to-back Yasuda Kinen victories in Tokyo on his last start in June, was an easy winner of his 1,000-metre trial after gliding past high-class sprinters Kenwood Melody and Prime Witness. Fairy King Prawn opened last season with a success in the Happy Valley Trophy over 1,200 metres, but Allan confirmed his stable star would start this term over a longer trip. 'I thought about running him again in the Happy Valley Trophy, but I think the tempo of 1,400 metres on the bigger track will be more suitable. Provided he pulls up OK from this trial, that's where he will run,' Allan said. 'Obviously, his immediate goal is the Hong Kong Mile, which is more than 10 weeks away. So, with that in mind, the horse is a little soft and I would be crazy to have him fully fit now. Fairy King Prawn will be better after a couple of runs but he will be as fit as I can have him without racing on Monday and fit enough to race well.' Owner Philip Lau Sak-hong was on hand to watch the trial and could find no fault with the effort, and nor could Fairy King Prawn's now regular jockey, Weichong Marwing. 'Ivan didn't have him fully wound up, of course, and the barrier trial will bring him on further,' Marwing said. 'But he went nicely. I would have to say I was very happy with how he galloped.' Connections remain mystified by Fairy King Prawn's failure in Japan, where he finished ninth as favourite and without any obvious excuse in the race. 'He looked fabulous, looked the way he did in Dubai,' Allan reiterated yesterday. 'He must just have been over the top the way he raced. But he appears to have come back as his old self.' Allan wins few trials and, tongue in cheek, he added: 'It must be going to rain - I've won two barrier trials today. I must remember to tell Weichong he is getting double his percentage for those wins.' Allan's only concern was the ground, which he felt was particularly firm yesterday. Allan will still be represented in the Happy Valley Trophy on October 10 by Cliffhanger and stayer Indigenous, who finished midfield in his trial yesterday but did everything Allan required. The trainer's grand stayer Oriental Express - who, along with Indigenous, is being aimed at the Hong Kong Vase on December 16 - is also entered for the National Day Cup. On a morning of high-class triallists, there was plenty of interest in David Hayes' new import, Danamite. The former New Zealand-trained four-year-old looked outpaced at one stage but wound up not too far away from the placegetters in the fifth heat, won by Galico. 'He is a bit switched off at the moment but I think one more good gallop and he'll be switched on,' Hayes said. 'Considering how much I've done with him at this stage, I was happy enough. The trials are just a training aid for him. He has run placings in three Group Ones in a row in Sydney so I don't need to use the trials to find out how good he is - his race form is proven.' Danamite is scheduled to make his first start in the Group Three Sha Tin Trophy over a mile on October 21. Hayes' top-grade miler Charming City was in the firing line in Fairy King Prawn's heat before dropping out in the final 200 metres, but that was in keeping with Hayes' pre-trial plan. 'His trial finished at the 600 metres as far as we were concerned, but even though he was held together after that it took until the last 100 metres before he dropped off so it was a nice effort,' Hayes said. 'Charming City will run in the Happy Valley Trophy and so will Prime Witness, who also trialled very well, I thought,' Hayes added. 'There is a bit of improvement in them from the trials. I've found this year that leaving a bit of freshness in the horses has been the key. These 1,000-metre trials are not quite races but they are hard enough to take the edge off the horses if they are given a strong trial too close to a race.' Caracoler, Hayes' other high-rated import, was unplaced in his trial and Hayes plans to step him up to an 1,800-metre race in Class One after he finished down the field in the HKSAR Chief Executive's Cup over 1,200 metres on his first Hong Kong start. Marwing was also aboard David Oughton's Hong Kong Gold Cup winner, Idol, who looked good yesterday as he trialled over a mile. Idol had a slightly disappointing season after his Gold Cup success, but is another slated for the Sha Tin Trophy as his kick-off race.
