Constitution Hill the star name in Aintree entries on opening day of Grand National Festival

Constitution Hill will face a maximum of 10 rivals when he bids to crown his fantastic campaign with victory in the William Hill Aintree Hurdle on Thursday.

Nicky Henderson's stable star has graduated to open company with honours this term – slamming top-class stablemate Epatante in the Fighting Fifth at Newcastle and the Christmas Hurdle at Kempton before his brilliant display in the Champion Hurdle at the Cheltenham Festival last month.

The six-year-old will be long odds-on to stretch his unbeaten record to seven on Merseyside before connections decide whether to head down the same route next season or pursue a career over fences.

Epatante won the Aintree Hurdle last season and could take on her esteemed stable companion again.

Gordon Elliott has entered Champion Hurdle third Zanahiyr, who could be joined on the trip from Ireland by stablemate Fil Dor, the Willie Mullins-trained Sharjah and Oliver McKiernan’s Meet And Greet.

Olly Murphy could saddle both Brewin’upastorm and Itchy Feet, with I Like To Move It (Nigel Twiston-Davies), Sceau Royal (Alan King) and Knappers Hill (Paul Nicholls) the other contenders.

The Aintree Hurdle is preceded by Alder Hey Aintree Bowl, which promises to be a fascinating affair.

Nicholls looks set to run Cheltenham Gold Cup runner-up Bravemansgame, while Henderson has stated his intention to step Shishkin up to three miles for the first time under rules.

With a late fall in the Sky Bet Chase at Doncaster in January effectively ruling out a tilt at the Grand National, Ga Law could take in the Bowl after finishing fifth in the Ryanair Chase last time.

Gold Cup third Conflated (Elliott), Gold Cup faller Ahoy Senor (Lucinda Russell) and last year’s Gold Cup winner A Plus Tard (Henry de Bromhead) also
