Caernarfon is reminding Jack Channon of some of the great fillies of his past ahead of her tilt at the Betfred Oaks at Epsom on Friday.

The daughter of Cityscape provided Channon’s father Mick with success in the Montrose Fillies’ Stakes last autumn and it would be somewhat fitting if she was to build on her 1000 Guineas fourth and provide the younger Channon with a Classic victory in his first season since taking over the training licence at West Ilsley.

As well as assisting his father, Channon has previously spent time working for Clive Brittain, and having been encouraged by what he has seen from Caernarfon since Newmarket, is now looking forward to her next big-race assignment, believing she compares favourably with some former top-class fillies.

“We’re really excited and she ran an absolute belter in the 1000 Guineas,” said Channon.

“I’ve been very lucky to have been around some very good fillies in the shape of Rizeena and obviously some of dad’s very good fillies – Samitar, Queen’s Logic, Music Show, Nahoodh and all those – and it’s very exciting to have one again. They are very hard to come by, but she gives me a similar feel to some of those good ones.”

Caernarfon was staying on strongly in the closing stages of the 1000 Guineas but will now have to prove her stamina as she takes the leap up to a mile and a half on the Downs.

However, Channon has always felt she would benefit from tackling further than a mile and is quietly confident she will take the challenge of the Oaks in her stride.

He continued: “Her work has taken a step up since Newmarket and she did a wonderful piece of work on Friday that has got everyone very excited. We’re quietly hopeful she stays.

“We felt going into the Guineas she would benefit from going up to a mile and a quarter. It’s one of those where we don’t know if she will stay a mile and a half but she has all the assets to and she looks a stayer physically, even if her pedigree doesn’t reflect that.

“The way she runs and the way she races will say there is a chance and she looks to have improved a bundle since the Guineas.

“Her work has improved immeasurably and her well-being and her coat and everything else, I couldn’t be happier with. We’re excited to give it a whirl.”

Frankie Dettori is optimistic Arrest can provide him a dream success in his final Betfred Derby on Saturday week after putting the colt through his paces at Epsom on Monday morning.

The son of Frankel emerged as a major contender for the premier Classic when demolishing his rivals in the Chester Vase on very soft ground earlier this month, after which joint-trainer John Gosden was hesitant to fully commit his sizeable three-year-old to a run at Epsom on June 3.

But after successfully traversing Tattenham Corner and seemingly handling the cambered track in a workout just short of a mile at the Derby Festival Gallops Morning, he looks set to take his chance.

Dettori, who in December announced 2023 will be final year in the saddle, will be bidding for a third Derby success following the victories of Authorized in 2007 and Golden Horn, and is delighted to be partnering a horse with leading claims on what will be his 28th and final ride in the great race.

“It’s all about getting used to the course and the most crucial part is Tattenham Corner, where horses can really win or lose a race,” said the 52-year-old Italian.

“He went round there fine. In the straight, it took him a furlong to get organised but he’s a big horse. He then went very straight and I was very happy with him.

“I have been fortunate enough to win the Derby twice and it is still the most famous race in the world for us. When I started my career as a jockey, first of all you want to get a ride in it and then try to win it. I’ve had over 20 rides in it and this is my last go. At least I am going into my last Derby with a great chance.

“It looks a wide-open Derby and I haven’t seen any horse really dominating any of the trials – they all won, but nobody won by a really wide margin so it looks a competitive and open Derby.”

With Arrest proving he handles soft ground so well, Dettori is hoping conditions are again on the easy side next week.

He added: “He is growing up and getting stronger. The ground is an issue, but Andrew (Cooper, clerk of the course at Epsom) always does a great job and I haven’t ridden in a very fast Derby for a long time – it has always been good or good to soft and, fingers crossed, the rain will continue.

“Every week horses improve and we still have two weeks to go. I would expect this horse after the gallop today to go on a bit and it’s very hard to assess one year to the next. But I am very pleased with him – he looks great and has done well in the gallop this morning.

“We always thought a bit of him last year, but he was all frame and no muscle. He did well over the winter and Chester was great. In the other trials Passenger (third in the Dante Stakes) impressed me most – he’s not in the Derby at the moment, but I expect he will be (supplemented).”

Gosden, who trains Arrest in partnership with his son Thady, was similarly pleased with how Arrest took to the idiosyncratic Epsom track.

He said: “This horse can change gears, absolutely. He’s a big boy and he proved he stayed the other day (in the Chester Vase) when he handled the conditions. He doesn’t need it to be like that.

“He’s a big boy and they always say that when they’re leggy like that the track is trickier for them here, but Frankie said he got himself organised and came nicely on the bit down Tattenham Corner onto the straight – so he was pleased enough with him.

“I think it’s all about getting a feel for the track and not actually about finding out how fast they can go around the track today. I tend to save that for the following weekend. We clearly were pulling up at the half-furlong marker, we weren’t going to the finish line and then rolling off down the hill, so it was very much an exercise gallop and not a test of ability.

“He was touched off in the Group One over a mile and a quarter at Saint-Cloud last year, so he was in the Derby then and he was the only one I had that was likely to come to the Derby and put up a bold show. You’re always lucky if you’ve got more than one to look at.

“It’s about 4-1 or 5-1 the field and to that extent he belongs right up there with them.”

Dettori is also set to team up with the Gosdens in the Betfred Oaks, with Soul Sister staking her claim for the fillies’ Classic with an impressive victory in the Musidora Stakes at York last week.

“John kept believing in her and when she ran at Newbury (finished last in the Fred Darling Stakes) his horses were not running that well,” said the jockey.

“At York she took me by surprise as she quickened twice, travelled and clocked a very good time. I was impressed.

“She has to go an extra two furlongs in the Oaks, but the signs are good. Obviously the (Aidan) O’Brien filly (Savethelastdance) who won by 22 lengths at Chester and is going to be hard to beat, but we’ll give it a go.”

The Jockey Club is taking every possible precaution to prevent the Betfred Derby at Epsom being disrupted by protesters, saying it has “robust security measures” in place.

The Grand National at Aintree was delayed a little over 10 minutes by animal rights group Animal Rising, with attempts to disrupt the Scottish National at Ayr the following weekend thwarted by police and security staff.

Epsom is owned and run by the Jockey Club and meetings with Surrey Police have taken place to make sure everything possible is done to ensure the two-day fixture runs smoothly.

However, the vastness of the area which needs securing, including public areas where people do not require tickets, presents obvious challenges. A handful of protesters made it onto the track before last year’s race, but were swiftly dealt with.

Nevin Truesdale, chief executive of the Jockey Club, said: “As part of our planning for the Derby Festival, we have been working with Surrey Police to ensure we have a range of robust security measures in place to protect the safety of everyone at the event, especially our equine and human participants, which will always be our number one priority.

“While we completely respect anyone’s right to peaceful and lawful protest, we would condemn illegal and reckless plans to breach security in an effort to disrupt the action on the track and endanger the safety of the participants in the strongest possible terms.

“Thousands of people look forward to attending the Derby every year and millions more will be watching at home and around the world, so we look forward to staging what is not only an important event for the sport but an iconic moment in the British summer and a celebration of the Thoroughbred.”
