The 6-5 favourite, ridden by Paul Townend, beat Captain Guinness to take the 225,080 pounds ($271,964) prize pot and give trainer Willie Mullins his 92nd Festival victory.

Bloom was also reported by British media to be the punter behind two bets totalling 600,000 pounds on the horse, making a profit of 830,000 pounds.

"He has done me proud. He ran a magnificent race and totally deserved to win," said Bloom.

"We are so fortunate to have such an amazing horse. He didn't run at his best last time out but has shown his class today."

Townend said Energumene had been "perfect everywhere".

"He jumped brilliant. You don't win champion races in that manner normally. He's a pleasure to ride," Townend told the BBC.
