In an unexpected twist, Bonjoy’s impressive campaign has been extended for another week.

Plans to send the talented mare for a spell and prepare her for a Group 1 campaign later in the year have been temporarily put on hold.

Trainer Jason Miller confirmed that despite missing the Detonator Stakes (1800m) due to a foot abscess, Bonjoy is back in action and set to contest Saturday’s Listed Sheila Gwynne Classic (1400m) at Ascot.

“She’s in great shape and feeling terrific,” Miller said.

“She’s been racing well for a while now, and this will be her final run before a well-earned spell.

“A three-month break lines up perfectly for her, and with only four runs this prep, she hasn’t been overworked.”

Bonjoy has been on a sensational winning streak at Ascot, securing three straight victories since November.

She cemented herself as a key player in the Ascot carnival with wins in the Listed Starstruck Classic (1600m) and two $100,000 events—the Celebration Of Life Day Trophy (1500m) and the Ascot Mile (1600m).

However, her momentum was briefly halted after she was scratched at the barriers in the Jungle Mist Classic (1200m) and later sidelined due to foot issues, missing the La Trice Classic (1800m) and Detonator Stakes (1800m).

For the Sheila Gwynne Classic, Bonjoy will carry the 58.5kg topweight and reunite with regular jockey Clint Johnston-Porter.

The pair will jump from barrier five in the 10-horse field.

Despite a 39-day gap between races, Miller has not increased her workload.

“I’ve actually eased off her training,” he said.

“She’s already got a solid fitness base and will come in with some freshness in her legs.”

Bonjoy’s rapid rise and sharp turn of foot over the past five months have given Miller confidence that she can compete at Group 1 level, with the Railway Stakes at the Ascot carnival firmly on the radar.

Early on, he rated her slightly ahead of stablemate Admiration Express, who nearly caused an upset when finishing runner-up to Light Infantry Man in last December’s Group 1 Northerly Stakes (1800m).

Miller expects Bonjoy’s main rival in the Sheila Gwynne Classic to be Generosity, a promising mare trained by Simon Miller.

Generosity is second-up after flashing home for second behind Twain’s Angel in the Marjorie Charleson Classic (1200m).

“She’s a quality horse, and I have a lot of respect for her,” Miller said.

Simon Miller’s runners have enjoyed success in this race in recent years, with Amasenus (2022) and Stellar Vista (2023) claiming back-to-back victories.

Generosity will have a new rider in Lucy Fiore, who replaces Chris Parnham, and will break from barrier two.
