No stranger to success in the Centenary Sprint Cup (1,200m) and Stewards’ Cup (1,600m), master trainer John Size has loaded up with two runners in each of Sunday’s Group Ones as he bids to continue his hot form.

The 12-time champion Hong Kong handler has an incredible record in both features, claiming the Centenary Sprint Cup five times including four years in succession, and the Stewards’ Cup seven times in the past 23 years.

Size’s best chances of adding to his imposing record are Helios Express and Howdeepisyourlove, but they again face the daunting task of taking on the seemingly unstoppable Ka Ying Rising in the Centenary Sprint Cup.

Helios Express has been placed behind Hong Kong’s most exciting sprinter on his past three starts, including last time out when he was beaten only half a length in second in the Group One Hong Kong Sprint (1,200m).

Howdeepisyourlove has been placed behind Ka Ying Rising twice and comes off a fast-finishing victory over Magic Control in the Group Three Bauhinia Sprint Trophy (1,000m) on January 1.

“They both seem to be in good order and pretty good shape,” Size said.

“Helios has done well. It was a good run on international day and he’s had a bit of time to get over that, so he’ll probably run well again.

“Howdeepisyourlove seems all right after his win the other day. He’s run some very good races this season, so maybe he can improve on that.”

In the Stewards’ Cup, Beauty Eternal will bid to recapture his Group One Champions Mile-winning form from last year after three indifferent runs this season.

The six-year-old produced arguably the best of those runs last start when a solid fourth to Voyage Bubble in the Group One Hong Kong Mile.

Red Lion will also represent Size in the feature, with the dual Group One placegetter coming off a last-start fifth to Patch Of Theta in the Group Three Chinese Club Challenge Cup (1,400m).

“Beauty Eternal’s good and his last run was quite sound,” Size said.

“Red Lion’s similar. He should benefit from another run [since the Hong Kong Mile]. Both horses are in good order, they just need a bit of luck to earn some prize money.”

Outside the Group Ones, Mickley shapes as an intriguing prospect for Size in the Class Two Able Friend Handicap (2,000m) on the quick backup from an unlucky 1,600m sixth last Sunday.

“He does look a little bit one-paced, so I think it’s an opportunity to see him at the trip and he’ll probably enjoy that, I think,” Size said of the Classic Series prospect. “The tempo might suit him.”

The former British galloper, who won second up at Sha Tin, could still tackle the Classic Mile on January 31.

“I’ll see how he runs on Sunday. We’ve got a couple of weeks to decide,” Size said.
