The Aidan O'Brien-trained gelding, twice a winner of the Champion Hurdle, will be aiming for his third successive victory in the Grade One contest. He fell to a shock defeat at the hands of Limestone Lad in the Duggan Brothers Hattons Grace Hurdle in November. "Istabraq is very well and I could not be happier. He's as enthusiastic as he was last year," O'Brien told Talksport. LATEST BIG-RACE ANTE-POST PRICES 686 Daily Quiz 685 BHB 691 Race News 661 Maguire Bellator Missile Powell
