Nicky Henderson’s Marie’s Rock is given another chance to advertise her staying talents in the rearranged SBK Warfield Mares’ Hurdle at Doncaster on Sunday.

The extended three-mile contest was originally scheduled for Ascot last Saturday before the cold snap forced a switch to Town Moor and Marie’s Rock’s owners, Middleham Park Racing, are thrilled their star mare gets the opportunity to run in a Grade Two event worth over £25,000 to the winner.

Her previous forays up to a staying trip have ended in defeat, but Middleham Park’s Tom Palin believes she has shown enough promise at the distance to be a major player in a race that also features Dan Skelton’s West Balboa, who was sent off favourite for the Grade One Long Walk Hurdle last month.

He said: “We’re very grateful for the fact that this race is going ahead. It looks a good opportunity for us to go back up to three miles.

“I do concede three miles is probably not her optimum and most effective trip – her championship trip. But that’s not to say she is ineffective over three miles and her ratings for her previous tries suggest she is capable of putting in a performance in the mid-to-high 140s, which in theory should see her competitive in this race.

“I don’t think she doesn’t stay it, she showed at Aintree she can get the trip. Is she a Grade One Stayers’ Hurdle contender over three miles? No. And that is why we are targeting the Mares’ Hurdle again at Cheltenham and is the only Festival entry she has got.

“However, I do think she is worth another crack at three miles in this Grade and amongst this company.”

The Cheltenham Festival winner was last seen chasing home Bob Olinger when defending her Relkeel Hurdle crown at Cheltenham on New Year’s Day, with connections content with the nine-year-old’s display against an on-song rival.

“I think we were as good as a Marie’s Rock aged nine could be last time against a resurgent Bob Olinger,” continued Palin.

“I wouldn’t have changed anything, almost nothing at all, about our Relkeel run – I think we did as well as we could and I would be supporting Bob Olinger wherever he runs next, that was a ridiculous performance from him.

“I thought we ran a really respectable race there and a repeat of that Relkeel performance should be enough to see her competitive here and to finish in the first five in a Mares’ Hurdle.

“You have to give West Balboa plenty of respect, she was backed into favouritism in the Long Walk. But we were backed into favouritism at Newbury, so it will be an interesting battle between them. We’re going to Doncaster full of hope we have found the right race for her and if everything goes to plan she should be competitive.”

Marie’s Rock is joined by a pair of Seven Barrows stablemates in Theatre Glory and Tweed Skirt, while Jamie Snowden’s Cheltenham Festival winner You Wear It Well tries three miles for the first time having finished well held in third in the Fighting Fifth last month.

Fergal O’Brien’s Dysart Enos will continue inching her way towards the Cheltenham Festival in the opening Download The At The Races App Novices’ Hurdle.

Amongst the favourites for the Mares’ Novices’ Hurdle at Prestbury Park in March, the six-year-old has done nothing but impress when maintaining her unbeaten record over hurdles this season.

She has now been found a fantastic opening to bank some more experience ahead of National Hunt’s showpiece meeting in just over six weeks’ time.

O’Brien said: “Neil (Jukes, race planner) can take all the credit for plotting this one and hopefully it’s a good opportunity for her to go and run without many penalties and she can turn up there and run her race and then look forward to the next one.

“I’ve been very happy with her since her last run, but more importantly Tom Broughton who rides her all the time says she is ready to go, so we will head to Doncaster on Sunday.

“I’ll probably be watching it from behind my fingers or behind a sofa somewhere and there won’t be a lot of pleasure in watching it, but we just need to get on and run her and I’m never afraid to get beat.

“You never know what is going to turn up on the day and we’ve just got to go and take our chance and hopefully do what we need to do.”
