Favourite Bobs Worth won the Cheltenham Gold Cup here on Friday to give trainer Nicky Henderson his second win in the blue riband of jumps racing in three years.
Bobs Worth, ridden by Barry Geraghty, beat home Irish challenger Sir Des Champs while Henderson's 2011 champion Long Run had to settle for third for the second successive year.
Bobs Worth had looked to be out of the running going over the third from home, where the fancied Paul Nicholls-trained Silivaco Conti came to grief, and the prize looked to be between the pacesetting Long Run and Sir Des Champs.
However, Geraghty, who had combined along with Henderson for the 19 length win of Sprinter Sacre in Wednesday's Queen Mother Champion Chase, had plenty left in the tank.
He had Bobs Worth alongside the leading duo at the penultimate fence and pulled clear before the last.
Sir Des Champs, though, rallied after the last under Tony McCoy and 33-year-old Geraghty had to pull out the stops to repel the challenge and take the honours.
It was Bobs Worth's fifth win from five races at the course, and his third at the Festival in as many years but testament to Henderson's training ability was only his first race in over 100 days.
