2012/2013: three-year-old season

In the autumn of 2012, Able Friend began his racing career in Australia by finishing second to Balzac at Rosehill Racecourse, and then recorded his first victory when taking a maiden race at Wyong on 22 November.^[8] In January 2013 he was sent to race in Hong Kong where he was trained by John Moore and owned by Dr & Mrs Cornel Li Fook Kwan. On his Hong Kong debut he carried 125 pounds and defeated thirteen opponents in a 1200-metre handicap race at Sha Tin on 8 June.^[9]

2013/2014: four-year-old season

Able Friend began his first full season in Hong Kong by finishing third in a handicap on 12 October, and then recorded wins in handicaps over 1400 metres in November and 1600 metres in December. In January the cgelding was stepped up in class for the Group 1 Hong Kong Classic Mile. Ridden by João Moreira, he was made the odds-on favourite and won by half a length from the Irish import Designs On Rome. After the race Moore said "This was the best Classic Mile field that I’ve seen since I’ve been in Hong Kong, and from that point of view, I think I’ve got the real deal on my hands; I believe he’ll be one of Hong Kong's leading lights in the future" whilst Moreira commented that the winner "could possibly be the best horse I have ridden".^[10]

Able Friend finished second to Designs On Rome over longer distances in his next two starts, being beaten one and a half lengths by his rival in the Hong Kong Classic Cup and by half a length in the Hong Kong Derby. He was then dropped in class and distance in April for the Group 2 Chairman's Trophy in which the Mauritian jockey Karis Teetan deputised for the suspended Moreira. After Able Friend the race by beating Packing Whiz and three others, Moore suggested that the horse might be sent to Royal Ascot for the Queen Anne Stakes. On his final appearance of the Hong Kong season Able Friend started 7/10 favourite for the Champions Mile ahead of a field which included California Memory, Gold-Fun, Dan Excel and Gordon Lord Byron. He proved the best of the locally trained runners but was no match for the South African challenger Variety Club and finished second, four lengths behind the winner.^[11]

2014/2015: five-year-old season

Able Friend was dropped back to sprint distances for his seasonal debut as his preparation race, at which he finished fourth to Aerovelocity when carrying 133 pounds in the 1200 metre handicap on 26 October.^[5] The gelding prepared for the Hong Kong Mile with a run in the Jockey Club Mile on 23 November. He started the odds-on favourite and won by two and a quarter lengths from Gold-Fun with Ambitious Dragon in third. The Hong Kong Jockey Club's report on the race likened Able Friend's dismissal of his opponents as resembling "a lion swatting flies".^[12]

On 14 December, Able Friend started the 4/6 favourite for the 24th running of the Hong Kong Mile. The ten-runner field included Grand Prix Boss (NHK Mile Cup), Hana's Goal (All Aged Stakes) and World Ace from Japan, while Britain was represented by Trade Storm (Woodbine Mile) and Captain Cat (Superior Mile). The locally trained opposition to the favourite was headed by Gold-Fun and Glorious Days. In the early stages Able Friend raced towards the rear of the field before being switched to the outside 400 metres out. He took the lead 200 metres from the finish and drew away to win by four and a quarter lengths from Gold-Fun with Grand Prix Boss in third. Following the race, Moore said "He's phenomenal. He's got that turn of foot and can relax and not waste energy, then he explodes when you show him daylight. I've got one of the best milers on the planet and we'll go for the Stewards' Cup and I'll try to convince the owner to go for the Duty Free."^[13]

On 25 January Able Friend started 1/4 favourite for the Stewards' Cup against a field which included Gold-Fun, Ambitious Dragon, Blazing Speed and Glorious Days. He was held up by Moreira before making rapid progress in the straight and won by one and a half lengths from Beauty Flame. After the race, Moore described the gelding as the best horse he had ever trained, ahead of Viva Pataca but admitted that "he's got to go overseas to prove himself".^[6] In March, Able Friend added a victory in the 1400 metre Queen's Silver Jubilee Cup despite being boxed in on the rail until the closing stages. On 7 April Able Friend took his winning run to five when he won the Chairman's Trophy for the second time. The gelding then started 1/4 favourite for the Champions Mile and won "very easily"^[14] from Rewarding Hero and Dan Excel. It was described as 'an absolute hand canter.' On his final appearance of the season, Able Friend was sent to Europe to contest the Queen Anne Stakes at Royal Ascot. He sweated badly and not on his usual calm demeanour before the race, and was never in contention, finishing sixth of the eight runners behind the French gelding Solow.

2015/2016: six-year-old season

Able Friend was off the course for four months before returning in the Premier Bowl at Sha Tin on 25 October. Carrying top weight over six furlongs he came from last to first in the closing stages to win by half a length from Gold-Fun. He then races in the Jockey Club Mile as a prep race for the Hong Kong Mile, but he disappointed the public by finishing only third. This raised speculations whether Able Friend could return to his best in the Hong Kong Mile in December 13. In that race, he had to face the challenge of the Japanese contingent Maurice, who won the Yasuda Kinen and the Mile Championship, thus generally regarded as the best miler in Japan of the generation. Therefore, the race has been built up as the battle for the crown of 'Asia's best miler'. Able Friend was found mildly lame with a sore off-fore hoof that morning, but was allowed to run after further examinations by the vets. He went past Maurice early in the straight, but the chestnut didn't sustain his run and Maurice fought back to win the race. Able Friend faded on his run so much he was also beaten by another horse at the end, finishing third. He hung out in the last 200M of the race like sore horses tend to do, which is suggestive that the lameness resulted in Able Friend's failure to finish in the way he can. The injury is most likely to be blamed for his defeat. It was reported on January 7 that Able Friend suffered from a rare tendon injury associated with the aforementioned lameness in the same right front foot. "He went into the Hong Kong Mile with a bruised sole, we kept him in minor work and the problem didn't resolve itself, " his trainer John Moore said, when he announced that his horse was sidelined for the rest of the season. The horse has been sent to a property in Australia on the Mornington Peninsula for rehabilitation.
