Henrietta Knight enjoyed her first day back on a racecourse as a trainer, despite being out of luck with two runners at Wincanton.

Neither Zettabyte or Ballywalter troubled the judge, but Knight, who during her first spell with a licence reached the summit of her profession, was welcomed back into the racing fold with open arms.

Knight enjoyed tremendous success during her first spell with a licence, winning the Gold Cup at Cheltenham three times with Best Mate.

She was also responsible for Queen Mother Champion Chase and King George hero Edredon Bleu, the Stayers’ Hurdle with Karshi and Victor Chandler Chase (now Clarence House) with Somersby.

Having competed at the highest level of equestrianism before beginning her training career, Knight was always credited with being a great horsewoman and until recently several trainers have sent their horses to her for extensive schooling.

“It was a very good experience to be back on the racecourse,” she said.

“I got a good welcome and I was among people I like being with.

“I saw plenty of people that I hadn’t see for a fair few years, but like myself they have all got a bit older!

“It was a great atmosphere and I’ve enjoyed it.”

She went on: “The first horse (Zettabyte) showed enough to suggest that he will win races in time, but I don’t know when I might have more runners due to the weather – judging by what they are saying there might not be much racing after Wednesday.

“Hopefully we can keep it all running smoothly at home anyway.

“I had such a lovely welcome today, I really enjoyed it.”

Zettabyte, formerly with Gordon Elliott, finished ninth of 15 having travelled well for a long way, while Ballywalter was pulled up at the third-last.

Henrietta Knight was out of luck with her first runner for over 11 years as Zettabyte finished unplaced at Wincanton.

Knight enjoyed tremendous success during her first spell with a licence, winning the Gold Cup at Cheltenham three times with Best Mate.

She was also responsible for Queen Mother Champion Chase and King George hero Edredon Bleu, the Stayers’ Hurdle with Karshi and Victor Chandler Chase (now Clarence House) with Somersby.

Having competed at the highest level of equestrianism before beginning her training career, Knight was always credited with being a great horsewoman and until recently several trainers have sent their horses to her for extensive schooling.

She had retired in 2012 but announced in November her intention to return and saddled her first runners at the Somerset venue.

While the seven-year-old Zettabyte, formerly with Gordon Elliott, failed to trouble the judge he did briefly suggest he might play a part in the finish suggesting there is something to work on for Knight.

The Start Your RacingTV Free Trial Now Handicap Hurdle was won by Anthony Charlton’s Ilanz (11-2).

Fontwell’s meeting on Thursday must pass a precautionary inspection at 8am due to the threat of frost.

Temperatures dipped to a low of minus 3.5C on Tuesday evening and are only due to rise to a high of 2C on Wednesday.

It could get even colder on Wednesday evening but there is hope that a daytime high of 4C may help thaw the track in time.

Wincanton on Friday is also under threat due to frost.

Having performed a minor miracle to get the course raceable on Saturday, clerk of the course Dan Cooper and his team now face a different problem.

The course is currently frozen in places and temperatures overnight could reach minus 3C before racing but a daytime high of 5C offers hope.

The meetings at Doncaster and Leicester on Wednesday both passed inspections before racing.

There were no issues at all at Doncaster but Leicester did need three inspections before getting the go-ahead, the latter at 12 noon.

It was an eventful start to the weekend for champion trainer Paul Nicholls but he is targeting more glory at his local track Wincanton on Saturday.

Nicholls’ Ditcheat yard was caught in a flash flood on Thursday evening, forcing staff to evacuate half a dozen horses from their stables.

However, as soon as the water levels rose they dissipated again, allowing Nicholls to resume his well-oiled routine.

So it will be business as usual for Nicholls, whose first runner Paddy De Pole in the Virgin Bet Novices’ Hurdle might be his least favoured of the four

“He won an Irish point-to-point in February at the sixth attempt and ran all right on his debut for us when keeping on to finish a distant third at Chepstow late last month. He will be suited by stepping up in trip here, but this looks quite a competitive race and he probably needs more experience before going handicapping,” said Nicholls.

Old favourite Magic Saint carries top-weight in the Virgin Bet Extra Places Handicap Chase and might just need the run.

“While he runs well fresh and handles soft ground he’s had a load of problems, is not easy to train and always improves for a run,” Nicholls told Betfair.

“He might be suited by starting at two miles. But I can’t be confident even though he has dropped a long way to a mark of 125 from a career-high rating of 159.

In the feature Virgin Bet Best Odds Daily Handicap Chase Huelgoat is another top-weight for the yard

“He loves Wincanton, will not mind the ground and Freddie (Gingell) won on him at this track in November so he should have a nice chance,” said Nicholls.

“I think you can put a line through his last run at Sandown where he didn’t stay the three miles. Harry Cobden blamed himself for being too positive on Huelgoat that day.”

Individualiste is another with strong claims in the Virgin Bet Daily Price Boosts Handicap Hurdle.

“He is turning out again quickly after hacking up at Taunton a week ago. It wasn’t the greatest race but he is only 4lb higher now and relishes heavy ground so must have a solid chance of following up with Freddie claiming 5lb.”

Oisin Murphy’s hurdles debut has been delayed after Thursday’s meeting at Wincanton was abandoned.

The three-times champion Flat jockey was due to have his first spin over obstacles aboard the Cian Collins-trained Lets Do This in the Danny McNab Bookmakers “National Hunt” Novices’ Handicap Hurdle at the Somerset track.

However, the fixture has been called off due to significant rain, with clerk of the course Daniel Cooper able to make a decision well ahead of the planned 8am inspection.

Cooper is also clerk at Exeter, where a 7.30am precautionary inspection on raceday will determine the prospects for Friday’s planned card.

Market Rasen hosts Thursday’s National Hunt action, with the ground reported to be soft, with heavy places on the chase track.

Sunday’s card at Huntingdon, which is scheduled to feature the Grade Two Peterborough Chase, is subject to a 2pm inspection on Thursday.

Cian Collins could record a unique double in providing Oisin Murphy with his first ride over hurdles at Wincanton on Thursday.

Collins helped close friend Denis O’Regan complete the full set of a winner at all the Irish and UK National Hunt tracks recently when Fiveonefive won at Hereford. Not long after that, O’Regan retired from the saddle a happy man.

Now Collins is hoping to provide another of his friends with a noteworthy success as Murphy, a multiple champion Flat jockey in the UK and nephew of three-times Gold Cup winner Jim Culloty, switches codes briefly.

Murphy rides the Collins-trained Lets Do This in the Danny McNab Bookmakers “National Hunt” Novices’ Handicap Hurdle.

“It’s created a bit of a stir on the internet I’ve seen, so hopefully it all goes well,” said Collins.

“We had Denis ride the winner at Hereford for us so hopefully this works out just as well, it would be nice.

“I can’t imagine riding over hurdles will be an issue for Oisin, he’s a top-quality horseman, it shouldn’t be a problem at all.

“I think the horse has a very good chance, hopefully, and let’s hope the meeting is on. They’ve had a dry day today so hopefully it should be.”

Three-time champion jockey Oisin Murphy is relishing the prospect of riding over hurdles for the first time at Wincanton on Thursday.

While most of the elite Flat riders are either enjoying some rare downtime during the winter, or plying their trade on foreign soil, Murphy will take up a new challenge in Dorset.

The 28-year-old is fresh from enjoying another successful campaign on the level, which yielded six Group One winners, including Classic success aboard Mawj in the QIPCO 1000 Guineas at Newmarket in May.

His mount on Thursday is the Cian Collins-trained Irish raider Lets Do This, who will contest the Danny McNab Bookmakers “National Hunt” Novices’ Handicap Hurdle.

Explaining his decision, the Killarney-born jockey said: “My uncle is Jim Culloty, who rode winners of the Cheltenham Gold Cup (Best Mate), Grand National (Bindaree) and Irish Grand National (Timbera) and also trained a winner of the Cheltenham Gold Cup (Lord Windermere).

“I worked with him in my teens, so jumps racing has always been part of my life and it has always been a burning ambition of mine to ride in a jumps race.

“I took out a jumps licence earlier in the year, as at one stage it looked like I might get a ride in the Champion Bumper at the Cheltenham Festival.

“The programme of Flat racing means it is unlikely that I will be able to ride over hurdles often, but this opportunity arose as I know the trainer and owner of Lets Do This well. It is only a fairly low-grade handicap hurdle on Thursday, so it seemed like a good place to start.

“I have been schooling horses to prepare, though have not yet ridden Lets Do This.”

Murphy is set to be well supported at Wincanton, adding: “Jim might be coming along to see me ride and my friend Denis O’Regan, who recently retired, might be travelling over from Ireland.

“I’ll be walking the course when I get to Wincanton to see what it’s like and will try and seek the advice of the jump jockeys riding there. I am really looking forward to the challenge.”

Several leading Flat jockeys have enjoyed success under both codes, perhaps most notably the late, great Lester Piggott, who partnered 20 winners over hurdles, including the 1954 Triumph Hurdle hero Prince Charlemagne.

More recently, the likes of Richard Hughes, Jamie Spencer and Tom Queally have combined the two disciplines and Murphy hopes to add his name to the list.

He said: “It would be an amazing feeling to get a winner over jumps and I’m not looking beyond Thursday at the moment – I just hope I don’t embarrass myself!”

Harry Cobden expects Rubaud to prove difficult to beat in Saturday’s West Country Weekend Elite Hurdle at Wincanton.

The Paul Nicholls-trained five-year-old had a progressive profile last season, which ended with him winning the Scottish Champion Hurdle at Ayr.

He showed there could be more to come this term when winning first time out in Listed company at Kempton last month, when connections expected him to need the run, and Cobden feels that bar Constitution Hill, Rubaud could take some stopping on his side of the Irish Sea.

“Rubaud is in good form after winning at Kempton the other day. The handicapper put him up 9lb for that, but you would want a good one to get by him here I would say,” said Cobden.

“He was impressive when he won the Scottish Champion Hurdle last season, but he was only running off a mark of 135 then. Now he is up to 150 and hopefully he can run up to that mark.

“I can’t think of too many horses in this country that would beat him in this division in Britain apart from Constitution Hill.

“He would struggle to lay a glove on Constitution Hill, but someone has got to win these races and we might as well keep him in this division and win as much as we can.”

Cobden went on: “He needed his first run as he hadn’t been away for a gallop. The runner-up at Kempton (Too Friendly) was race-fit and Rubaud was fresh.

“He can take a chance at his hurdles and the only thing I would say about his Kempton run was that he was bit low at the odd one, but he got away with it.

“That run will have taken the gas out of him and he is a horse that really wants it and he will stick his head out for you. He has got a nice way of galloping, and he has a nice low head carriage.”
