Jessica Harrington and Robbie Power followed up their Gold Cup success with Sizing John when Rock The World took the last race of this year's Cheltenham Festival, the Johnny Henderson Grand Annual Challenge Cup.
Power charged through on Rock The World (10-1) to lead at the final fence and storm up the hill to win from Gardefort ,with Theinval third and Dandridge fourth.
It was Ireland's 19th win of the week to Great Britain's nine.
Harrington said: "What a day. He was fantastic, that horse.
"He was third last year and he had a wind op after he ran here in the autumn. I couldn't run him at home as the ground was too heavy, so I gave him a couple of racecourse gallops.
"He loves quick ground, he absolutely loves it.
"He'a beautiful jumper. He's pinged the last and stayed on all the way up the hill.
"It's fantastic for me, I shall have a grin on my face for about a month."
