affie Osborne's year began with a ride on a 150-1 chance in a race worth £7,000 at Wolverhampton on 6 January, when she trailed in last of the seven runners. Its final chapter will open on Sunday in the decidedly glitzier surroundings of Sha Tin racecourse in Hong Kong, where Osborne has 10 rides on an 11-race card, and the 10 months in between have been transformational for the 24-year-old jockey.

A first top-10 finish in the Flat jockeys' championship was the reward for Osborne's consistency throughout the May-to-October title race, but the undoubted highlight was her victory on Highwayman victory in the St Leger in September. It was Osborne's first Group One win, and also the first for a female jockey in a British Classic.

It was a historic success that surely contributed to the Hong Kong Jockey Club's decision to offer Osborne a six-week pre-Christmas riding contract a couple of weeks later.

Hong Kong's punters, meanwhile, may be drawn to another key feature of her 2026 season: the consistency with which Osborne's mounts have outperformed their odds. Her 85 wins from 600 rides since from the start of 2026 returned a level-stakes profit of £31.81, while during the six-month championship race, the profit to a £1 stake was just under £100. In a racing hotbed that is focused entirely on betting, anything even close to that level of success would make Osborne an immediate star.

Hong Kong's racing industry does not have a breeding industry attached. Instead, its runners are imported from around the world, and 99% are geldings, which are easier to train, show more consistent form and tend to enjoy longer careers than "entire" male horses. Around 97% of its races, meanwhile, are handicaps, with full fields of either 12 or 14 runners (and a couple of reserves to ensure that any late gaps are filled).

Osborne will make her riding debut at Sha Tin, which stages racing every Sunday during the season, but had her first experience of Hong Kong's famously intense racecourse atmosphere at Happy Valley on Wednesday evening. "It's really cool to be able to experience it for the first time," Osborne said this week. "Having watched it on television so much, being able to see it in person was really surreal. It's an amazing atmosphere and a really unique track, and to be in the middle of such a vibrant city was very cool."

While Sha Tin is a broad, galloping track with sweeping turns that suits a long-striding horse, Happy Valley is a famously compact venue surrounded by skyscrapers, with tight turns and a high premium on getting a good early position. "Every place you go, races are run slightly differently, and I think it's just about adapting quickly," Osborne says. "There's such different, unique tracks in England and they all have their quirks and different ways of riding them. So you have to learn quickly, and I think that's something that will stand me in good stead here."

Such is the popularity of racing in Hong Kong that would-be owners need to join a waiting list, while 88 meetings over the course of last season generated $HK143bn (£13.5bn) in Tote betting turnover and a gross profit – after returning around 86% to the winners – of $HK20bn (£1.9bn).

"I was maybe slightly shocked that I had 10 rides [on Sunday], but very excited," Osborne said. "I've got a lot of homework to do before Sunday, but it's also really nice to pick up a ride in the feature race [on Silvery Breeze in the £400k Group Three Sa Sa Ladies' Purse Handicap]. Being so light, I can do bottom weight [of 8st 3lb], and that's something that's helped me a lot in the UK and hopefully it can help me here."

Hollie Doyle and Rossa Ryan will be two familiar faces riding alongside Osborne over the next few weeks, while Richard Kingscote, Harry Bentley and Andrea Atzeni are among former leading riders in Britain that are now based in Hong Kong full-time. Her most formidable rival, though, will be Australia's Zac Purton, who finished well clear in last year's standings to claim his ninth championship, ahead of Hugh Bowman, Atzeni and Karis Teetan.

"Obviously, I'd love to ride as many winners as possible, but I know how hard it is to ride winners here," Osborne says. "I think every place you go, you learn different things, and it furthers your skills as a jockey. And only being 24 and [in] my sixth year riding, you're still trying to learn as much as possible. [Hong Kong] has such world-class jockeys, so you just pick up things off of them."

Castle to scale heights in November Handicap

The November Handicap has not had a dual winner in its 150-year history, but both Lord Melbourne and (3.25), the winners in the past two seasons, are back for another crack at Doncaster on Saturday and William Haggas's gelding is a decent bet at around 9-1 to register a small piece of racing history.

Neither horse has run since last year's renewal, when Castle Cove was an easy four-and-a-quarter length winner with Lord Melbourne only sixth.

Castle Cove is 8lb higher in the weights this time around but won with a great deal to spare 12 months ago and has a hold-up running style that is well suited to Doncaster's long home straight.

Aintree 1.15 Paul Nicholls's string is in excellent form and while was winless last season, he resumes here after a wind op and 9lb below his last winning mark.

Aintree 1.45 was a fine third in the Supreme Novice Hurdle at Cheltenham and should confirm himself a significant Champion Hurdle contender here.

Doncaster 2.10 There is plenty of pace drawn high to give a tow into the race and he looks ready for this step up to Listed company after two wins in ultra-competitive handicaps.

Aintree 2.25 A luckless run when favourite for the two-and-a-half mile novice at Cheltenham in March in the only blip on record and he promises to be as good, if not better, over fences.

Doncaster 2.45 has yet to add to her debut success in October 2024 but has a series of useful efforts to her name at this level and is also proven with cut in the ground.

Aintree 3.00 The step up to three miles should be ideal for the lightly-raced who is not the slickest of jumpers but may find things a little smoother at a slightly easier pace.

Aintree 3.35 Jane Williams's has gone well off a break in the past and remains on a handy mark for his seasonal debut on the balance of his form last term.
