It is rare that husband and wife jockeys ride against each other in a top-class race, and it is rarer still that they ride for the same trainer.

Yet that is the prospect facing Tom Marquand and Hollie Doyle when they oppose each other in the Group One Tattersalls Falmouth Stakes at Newmarket on Friday.

Doyle is on the much-fancied Nashwa for owner Imad Al Sagar, while Marquand will sport the famous pink and green Juddmonte colours aboard Coppice, with both trained by John and Thady Gosden.

For racing’s ‘golden couple’, it is business as normal, as Doyle explained: “I’m obviously only riding because of Imad’s retainer, but it’s good that Tom has picked up that good ride.

“Riding against him in a Group One for the same team is not something I’ve really thought about – it would never really cross my mind. It’s just another day at the office.”

Third in last year’s Oaks, Nashwa went on to give Doyle a first Classic success when taking the French equivalent at Chantilly before recording a second Group One success in the Nassau at Goodwood and excellent placed efforts in both France and America.

However, she has failed to really sparkle in her two starts this term, at Chantilly and Newcastle, and Doyle is hoping she will finally be ready to show her true colours as she drops back to a mile for the first time in eight starts since landing a Haydock novice in April last year.

“I think she has taken a time to come to hand,” added Doyle. “She is really big and has grown a lot over the winter. I just think she has taken a few runs to get straightened out, really.

“John and Thady are clearly happy with the way she has come out of Newcastle to run her back in the Falmouth. We will leave it to them – they usually do the right thing.”

Marquand replaces the suspended Frankie Dettori aboard Coppice, who followed up her Newcastle novice success with victory in the Sandringham at Royal Ascot.

He said: “Obviously it’s fantastic to pick up a ride of Coppice’s quality in a major Group One.

“She comes in off the back of an impressive performance at Ascot with Frankie and under unfortunate circumstances for him, I’ve been lucky enough to have been given the opportunity to get aboard her, so hopefully she can continue along her progressive path.”

Barry Mahon, European racing manager for owner Juddmonte, feels it is a “nice opportunity” for Coppice to test her mettle.

He said: “This is a huge step up in class, but she’s a nice filly and she won well at Ascot.

“She’s a filly that we have Group-race aspirations for so we will start here and see how we get on and if we have to lower her sights, then we can. She’s a filly who, if she could get third in a Group One, then that would be a nice result.”

The George Boughey-trained Via Sistina, winner of the Pretty Polly Stakes at the Curragh just under two weeks ago, is a likely favourite but her participation hinges on some ease in the Newmarket ground.

Bookmakers see Ralph Beckett’s duo, Remarquee and last year’s winner Prosperous Voyage, as the biggest threats outside of Nashwa, with the former making her first outing for new owners Wathnan Racing on the back of her second to Tahiyra in the Coronation Stakes.

Meanwhile, defending champion Prosperous Voyage was a winner at Epsom before finishing third in the Duke of Cambridge Stakes at Ascot and returns to the scene of her finest hour with William Buick deputising for the suspended Frankie Dettori in the saddle.

“Hopefully the rain will hold off for her,” said Jamie McCalmont, racing manager for Marc Chan, who owns the filly with Andrew Rosen.

“Her last two runs have been good and she goes into the race as well as she did last year, so you would have to be really hopeful.”

Saffie Osborne maintains her partnership with Ed Walker’s Random Harvest, having finished a place behind Prosperous Voyage at Epsom, but a place in front of that rival at Ascot, while Never Ending Story (Aidan O’Brien), Ameynah (Roger Varian) and Astral Beau (Pam Sly) complete the line-up.

George Boughey will walk the track before deciding whether to let Via Sistina take her chance in the Tattersalls Falmouth Stakes at Newmarket on Friday.

The improving five-year-old broke her Group One duck last time out over 10 furlongs in the Pretty Polly at the Curragh.

She is due to drop back down to a mile on the July course but Boughey says there must be enough ease in the ground to enable her to show her best.

“We will work as if she is running but she needs the rain for her to run,” he said.

“The Falmouth has always been a plan for her as she does look very good on a straight track, but softer ground is key to her.

“There are lots of times she could run where she will get soft ground and we are not going to do anything that is not in the best interests of the horse.

“If it did rain, she will be very competitive. We will walk the track and if it is the same as Ireland last time I imagine she will take her chance, but if it is any faster she won’t.

“For her pedigree, if she was to win a Falmouth she would be pretty sexy.”

Via Sistina is one of nine declared for the one-mile Group One that headlines Friday’s action, with a stellar cast lining up on the July course.

Defending champion Prosperous Voyage is one of two for Ralph Beckett and is joined by Royal Ascot runner-up Remarquee, with the Coronation Stakes second making her first outing for new owners Wathnan Racing.

John and Thady Gosden are also double-handed as they saddle not only last year’s Prix de Diane winner Nashwa, but also the Juddmonte-owned Coppice.

The Sandringham scorer was partnered by Frankie Dettori when triumphing at the Royal meeting, but with the Italian serving a ban picked up at the summer’s big week, Tom Marquand picks up a rare Clarehaven ride and deputises aboard the progressive three-year-old.

Ed Walker’s Random Harvest is another to bring smart Royal Ascot form to the table, while Roger Varian’s Ameynah was last seen finishing sixth in last year’s 1000 Guineas and returns from 439-days off the track.

Pam Sly’s Astral Beau and Aidan O’Brien’s Never Ending Story complete the field.
