Quevega rewrote jumping history when winning the same race for the fifth successive year at the Cheltenham Festival.
The nine-year-old mare completed a nap-hand of victories in the OLBG Mares’ Hurdle in dramatic fashion to make it a treble on the day for jockey Ruby Walsh and trainer Willie Mullins.
In doing so she equalled the feat of Golden Miller, who won the Gold Cup from 1932 to 1936.
Her cause looked hopeless, though, when she almost came down after clipping heels at the top of the hill.
Walsh kept his cool and let her regain her rhythm before asking her to pick up ground.
She had lots to do as French raider Sirene D’Ainay made the best of her way home, but Quevega (8-11 favourite) picked her off up the hill to win by a length and a half.
Swincombe Flame was another two lengths away in third.
Walsh said: “We were very, very lucky. I’m not sure if she stood on herself or clipped heels with something else, but she was on the floor at the top of the hill - she nodded and I nearly fell over her ears.
“When she stood back up then, the boys were gone, and I had to sit and suffer down the hill, but she has a tremendous little engine.
“She has a wonderful attitude and you’d have to say she’s trained by a genius. She jumped the last and, my God, did she battle.”
Sam Waley-Cohen punched out Rajdhani Express (16-1) to claim a thrilling triumph in the Rewards4Racing Novices’ Handicap Chase.
The amateur, who partnered Long Run to win 2011 Gold Cup and will be back on board the same horse on Friday, appeared confident coming down the hill.
He began to assert on the run down to the final fence and held off Ackertac by a neck to strike in the colours of the rider’s father, Robert Waley-Cohen, the Cheltenham chairman.
It has also been a memorable few days for the rider following the recent birth of his first child.
It was a double on the day for trainer Nicky Henderson after the success of Simonsig in the Racing Post Arkle Trophy.
Jockey Brendan Powell jnr enjoyed his first winner at the meeting when storming to victory on Golden Chieftain in the JLT Specialty Handicap Chase.
The 3lb claimer, who is the son of former top jumps jockey Brendan Powell snr, got a good tune out of the bottom weight, trained by Colin Tizzard.
Golden Chieftain (28-1) came through to tackle Our Mick, and shrugged him aside before galloping on strongly to score by 10 lengths.
