Hong Kong racing has produced many prominent ownership families, but few have maintained such a broad and sustained presence as the family of Martin Siu Kim Sun. Across several generations, members of the Siu family have owned dozens of horses, contested Hong Kong’s most important races and carried their distinctive red-and-black colours onto the international stage.
Hong Kong Jockey Club ownership records demonstrate the scale of the family’s involvement. Siu Pak Kwan has been associated with 30 horses, while Martin Siu Kim Sun’s list includes 20 registered runners. Edmond Siu Kim Ping has raced 23 horses, Siu Kim Ying has owned 13, and Virginia Siu Leung Hiu Bing and Jocelyn Siu Yang Hin Ting have each been represented by five. Taken together, the records reveal an ownership tradition extending far beyond the achievements of one individual or one exceptional horse.
Unlike families whose horses share a single prefix, the Sius have used a wide range of names. Siu Pak Kwan’s representatives have included IRIAN, MR MEDICI, BULLISH CASH and POLARIS, while Martin Siu’s horses have included TIME WARP, THEWIZARDOFOZ, FREDERICK ENGELS, ARIEL and CORLEONE. Edmond Siu’s ownership record contains another extensive group, including ANODE, MICKLEY, RAINBOW CHIC, SUPER CHIC and TIGRE DU TERRE.
The family’s identity therefore comes not from a repeated naming formula, but from continuity. Horses have been registered under different family members and sent to different trainers, yet the familiar red-and-black striped silks have provided a link between each stage of the story. An official Hong Kong Jockey Club feature on WAIKUKU described the Sius as an established racing family and identified TIME WARP and IRIAN among their notable performers.
One of the horses who first established the family at the highest level was IRIAN. Owned by Siu Pak Kwan, the German-bred gelding competed 35 times, recording two wins, four seconds and two thirds while earning HK$18,410,238. His overall winning total may appear modest, but it does not fully reflect the quality of races in which he competed.
IRIAN’s most important victory came in the 2010 Jockey Club Cup over 2,000 metres. He then came within a neck of winning that year’s Hong Kong Cup, finishing second in one of Hong Kong’s most important international races. He returned to finish runner-up in the Hong Kong Cup again in 2011 and also travelled to Singapore, where he took third in the Group 1 Singapore Airlines International Cup.
Those performances made IRIAN one of the family’s first consistently competitive international-level middle-distance horses. Although he did not secure a Group 1 title, he repeatedly demonstrated that the Siu colours belonged among the strongest runners in Hong Kong and could also be competitive overseas.
The horse who elevated Martin Siu Kim Sun’s ownership achievements to an entirely different level was TIME WARP.
A British-bred gelding trained by Tony Cruz, TIME WARP became famous for his bold front-running style. Rather than waiting for the closing stages, he was at his best when allowed to establish a rhythm in front, stretch the field and challenge his rivals to catch him. From 44 starts, he recorded seven wins, three seconds and four thirds, accumulating HK$39,640,050 in prize money.
His first major Hong Kong breakthrough came during the 2017/18 season. After winning the Group 3 Ladies’ Purse, TIME WARP progressed to the 2017 Hong Kong Cup. He went forward, controlled the 2,000-metre contest and maintained his advantage in the home straight to win by two and a quarter lengths. It was Martin Siu’s first victory in one of Hong Kong’s four international Group 1 races.
TIME WARP confirmed that success in the 2018 Hong Kong Gold Cup. Once again allowed to dictate from the front, he completed the 2,000 metres in 1m 59.97s and defeated his rivals by half a length. The performance established a new Sha Tin course record at the time, although the mark was subsequently lowered by his full brother GLORIOUS FOREVER.
At the end of the campaign, TIME WARP was named Hong Kong’s Champion Middle-Distance Horse. Martin Siu received the award on behalf of the gelding, marking one of the most important achievements in the family’s long ownership history.
TIME WARP’s career also demonstrated the patience required to maintain an older horse at the highest level. His form fluctuated after his championship season, but he continued to contest elite races and returned to his best in February 2020.
In that season’s Hong Kong Gold Cup, TIME WARP again adopted his preferred front-running tactics. Almost two years after his previous Group 1 success, he held on to win by three-quarters of a length, becoming a two-time winner of the race. His victory proved that even after numerous demanding contests, he retained the ability and determination to defeat Hong Kong’s leading middle-distance horses.
With three Group 1 victories—the 2017 Hong Kong Cup and the Hong Kong Gold Cup in 2018 and 2020—TIME WARP became one of the most successful horses ever owned by the family. His racing style also made him especially memorable. Every major appearance carried an element of suspense: if he could establish a comfortable lead, the rest of the field often faced a difficult task trying to catch him.
While TIME WARP represented Martin Siu at the highest level over 2,000 metres, another branch of the family found an outstanding performer over shorter distances.
WAIKUKU raced in the colours of Jocelyn Siu Yang Hin Ting and was trained by John Size. The Irish-bred gelding arrived in Hong Kong in September 2018 and made an immediate impression. After finishing a narrow second on his local debut, he won four consecutive races and climbed rapidly through the handicap ratings before entering the 2019 Four-Year-Old Classic Series.
Although WAIKUKU did not win the Hong Kong Derby, his greatest achievements came after he moved into open-age competition. He developed into an elite performer between 1,400 and 1,600 metres, combining tactical speed with a powerful finishing effort.
His first major success came in the 2019 Jockey Club Mile. Two months later, WAIKUKU captured the 2020 Stewards’ Cup, securing his first Group 1 victory over the Sha Tin mile. He added the Queen’s Silver Jubilee Cup over 1,400 metres in 2021 and won the Stewards’ Cup for a second time in 2022.
WAIKUKU completed his Hong Kong career with eight wins, five seconds and four thirds from 33 appearances. His prize money of HK$47,062,450 surpassed even TIME WARP’s total, while his final rating of 113 reflected the high level at which he competed.
His three Group 1 victories also showed the breadth of the family’s racing success. TIME WARP had excelled as a front-running middle-distance horse, while WAIKUKU became a leading 1,400 and 1,600-metre performer. Together, they gave the Siu family major victories across different distances, tactical styles and ownership branches.
The family’s wider record contains many other useful and talented horses. Siu Pak Kwan’s ownership list stretches from earlier representatives such as IRIAN, MR MEDICI and BULLISH CASH to more recent registrations including COLUMBUS, NAVAL FORCE, KOLONEL and POLARIS. Edmond Siu Kim Ping has maintained another substantial string, with names such as ANODE and MICKLEY continuing the family’s presence in recent seasons.
Martin Siu’s own list also demonstrates the variety of horses that have carried his colours. THEWIZARDOFOZ won several races during the earlier part of his career, while FREDERICK ENGELS competed in Hong Kong’s higher sprinting grades. More recently, ARIEL and CORLEONE have maintained his active involvement at Sha Tin and Happy Valley.
ARIEL has proved a particularly durable member of the modern team. The British-bred gelding recorded four wins and four seconds from his first 41 Hong Kong starts, earning HK$11,236,850. Although he did not reach the Group 1 heights of TIME WARP, his ability to compete over several seasons provided the kind of consistent service that remains important to any long-term owner.
CORLEONE offered further encouragement during the 2025/26 campaign. The Australian-bred gelding won three of his first 11 races, in addition to two seconds and one third, while earning HK$3,534,740. His rating rose from 51 at the beginning of the season to 74, illustrating the steady improvement that owners hope to see as a relatively inexperienced horse adapts to Hong Kong racing.
The contrast between TIME WARP and CORLEONE also captures the full nature of the ownership journey. At one end stands a proven international Group 1 champion with almost HK$40 million in earnings. At the other is a developing handicapper still progressing through the grades. Both, however, form part of the same continuing story.
That willingness to begin again is essential to the longevity of any racing family. Champions eventually retire, promising imports do not always fulfil expectations and even the most carefully selected horse may struggle to adapt. Maintaining a significant ownership presence therefore requires more than celebrating major victories. It requires patience, repeated investment and an acceptance that every new horse begins with uncertainty.
The Siu family’s record reflects that reality. IRIAN came close to international Group 1 glory without quite achieving it. TIME WARP developed into a three-time Group 1 winner and champion middle-distance horse. WAIKUKU found his greatest success after missing out in the Four-Year-Old Classic Series, eventually becoming a three-time Group 1 winner himself. Other representatives have contributed through handicap victories, consistent placings or simply by carrying the family colours into another season.
From IRIAN’s international placings to TIME WARP’s front-running triumphs, and from WAIKUKU’s elite mile victories to the continued progress of horses such as CORLEONE, the family’s success cannot be attributed to one fortunate purchase.
It has been created over many years, through numerous horses and across several members of the family. Trainers and racing generations have changed, but the red-and-black identity has remained visible.
The story of Martin Siu Kim Sun and his family is therefore not defined solely by the trophies won by TIME WARP or WAIKUKU. Its deeper significance lies in continuity—the willingness of one generation to maintain the involvement established by another and to keep searching for the next horse capable of competing at the highest level.
As long as the Siu family’s red-and-black colours continue to appear at Sha Tin and Happy Valley, the legacy established by IRIAN, TIME WARP and WAIKUKU will remain part of Hong Kong racing’s unfolding story.
