Kargese delivered a stunning upset in the Singer Arkle Challenge Trophy Novices' Chase at Cheltenham, winning at 7-1 odds against market favorites. Danny Mullins executed a flawless front-running ride on the mare, who maintained her pace turning for home and held off challenges from stablemate Kopek Des Bordes and Nicky Henderson's Lulamba. The victory came by two and a quarter lengths.

The race took an unexpected turn as jumping errors from the two market leaders proved costly. Willie Mullins revealed Kargese's superior experience played a crucial role, noting she had far more racing knowledge than her stablemate. The trainer expressed relief that both his runners finished strongly without the dramatic fall that had previously affected Annie Power in similar situations.

Kargese's performance showcased her toughness, with Mullins describing her as "a really tough nut" who consistently gives herself hard races. The victory marks a significant achievement for the Mullins team at Cheltenham, with the trainer suggesting the mare could be a future Champion Chase contender. The race was overshadowed by tragic news that Gary and Josh Moore's horse Hansard suffered a fatal injury following the event.
