Ruby Walsh has admitted Annie Power's exuberance would be a slight concern if she runs in the Ladbrokes World Hurdle at the Cheltenham Festival.

Willie Mullins' unbeaten mare stretched her unbeaten record to 10 races at Doncaster on Saturday but she was noticeably keen before the race.

Annie Power has three options in March - the Champion Hurdle, the David Nicholson Mares' Hurdle and the World Hurdle over three miles.

"I don't think any of the three races would inconvenience her," the jockey told Racing UK.

"Does she have enough experience over two miles for a Champion Hurdle, do you want to expose her to At Fishers Cross and Big Buck's over three miles and risk emptying her out, or do you throw her in against Quevega? Thankfully, I don't have to make that decision.

"She's a good mare. The most impressive she was for me was at Cheltenham against Zarkandar. I have no worries about her getting three miles.

"Even last year when she won a Grade One over two and a half miles the further we went the better she went, but she doesn't lack pace.

"She was more on her toes at Doncaster than she has been any other day but she's always been highly-strung - so that (going over three miles at Cheltenham) would be a worry. But that's part of every big race, how they handle the parade and the build up.

"I wish I had a say in which races they ran in but I have none. It's the downside of having a good job, having to choose between good horses, but that's life."
