Henderson's dozen-up for Betfair
Henderson, who has won the race four times, will send out 2009 Champion Hurdler Punjabi and also has course and distance winner Lyvius and the promising trio of Forgotten Voice, My Tent Or Yours and River Maigue in his list of entries.
Paul Nicholls, trainer of last year's winner Zarkandar, has seven potential runners, led by Pearl Swan and Caid Du Berlais while Jonjho O’Neill has entered Get Me Out Of Here, his 2010 Betfair Hurdle winner, for the £152,500 race, is the richest event of its kind in Europe.
More than a quarter of the entries hail from Ireland with seven-times Irish Champion National Hunt trainer Willie Mullins responsible for five of those.
The seven-race programme will include two valuable Group 2 chases in the Betfair Denman Chase and the Betfair Super Saturday Chase.
