Minella Indo won a thrilling Cheltenham Gold Cup under Jack Kennedy to deny Rachael Blackmore aboard A Plus Tard in a 1-2 for trainer Henry de Bromhead.
The 9-1 winner held off the runner-up by one and a quarter lengths with two-time champion Al Boum Photo in third.
Blackmore, the leading Cheltenham Festival rider with six wins this year, was looking to become the first female jockey to win the big race.
De Bromhead had earlier this week won the Champion Hurdle and Champion Chase.
