Bryony Frost will be on the sidelines for a couple of days following a fall while schooling on Monday.

Frost, who has been in a rich vein of form in recent weeks, hopes to be back in action at Ascot on Friday and then again on Saturday when she is due to ride the Paul Nicholls-trained Red Risk in the Howden Long Walk Hurdle.

She had been due to ride at Fakenham on Tuesday and Newbury on Wednesday, but has sat those out in an attempt to ensure she is fit for the weekend and, further ahead, the ride on Frodon in the King George on Boxing Day.

Her agent Iain Turner said: “She’s had a spill while schooling and we’re planning on her being back at the weekend.

“It’s one of those – with Boxing Day coming up it’s just a case of not taking any risks, which is frustrating as she had some nice chances at Fakenham.

“She’s been on a good run since her injury, and of course she was just touched off in the December Gold Cup on Il Ridoto on Saturday so this has just halted everything.

“As far as I know everything is set for her being back at Ascot on Friday, then she’s got Red Risk in the Long Walk and Frodon on Boxing Day to look forward to.”

Middleham Park hurdlers Red Risk and Marie’s Rock are likely to cross paths in the Long Distance Hurdle at Newbury next month.

Both horses run in the silks of the ownership group, and Marie’s Rock has won at the highest level for connections, taking both the Close Brothers Mares’ Hurdle at the Cheltenham Festival and the Mares Champion Hurdle at Punchestown last year.

The Nicky Henderson-trained mare was second to Sire Du Berlais in the Liverpool Hurdle on her final start last season and will reappear for the new campaign over the staying trip.

There she will encounter Paul Nicholls’ Red Risk, an eight-year-old who has been moving out of handicap company in recent starts and made a promising start to the season when second in the Grade Two bet365 Hurdle at Wetherby’s Charlie Hall meeting.

Tom Palin of Middleham Park said of the two horses: “I think they’re going to do battle, they’ll be taking each other on at Newbury in the three-mile Grade Two there (December 1).

“That’s been Marie’s Rock’s target for a while, that was the logical starting point for her.

“Red Risk ran a cracker at Wetherby, I thought we were going to go past the other horse but he really toughed it out as well. We were delighted with the run.

“He does go very well fresh, we’ll run at Newbury but the one question we have is whether it’s a bit too soon after Wetherby.

“Then we’d just look at giving him a bit of a freshen up going into something ahead of the spring, maybe a Cleeve Hurdle or something akin to that.

“They’ll probably end up taking each other on at Newbury in that Grade Two and it will be fascinating to see who comes out on top.”

Marie’s Rock will proceed from Wetherby in the direction of the top staying contests, with the big festivals at Cheltenham and Aintree pencilled in for the spring.

“She’s obviously got that useful weight allowance and I think she has a pull as it is on official ratings but that performance (by Red Risk) the other day was a very, very good performance,” Palin said.

“We’ve just got Red Risk figured out and Marie’s Rock is in great form. Her campaign kind of plans itself; Newbury, Ascot, Cheltenham for the Cleeve, Cheltenham for the Stayers’ and Aintree again.”
