David Hayes has had a major change of direction with his gun colt Fast ‘N’ Rocking, who will now miss the $1 million Caulfield Guineas (1600m). Hayes says Fast ‘N’ Rocking has failed at 1400 and 1600 metres and he now believes the horse is a run-on sprinter, like his champion sire Fastnet Rock.

Hayes told racingvictoria.net.au he would freshen the horse for the Group 1 $500,000 Coolmore Stud Stakes down the 1200-metre straight course at Flemington, on Derby Day.

“He has failed three times in his life, twice at 1400m and once at a mile (1600m),” Hayes said.

“I think at the moment that he’s just a sprinter like his father.

"I’ve always been worried in the back of my mind since the Champagne Stakes (1600m) that he doesn’t run a mile but I thought that it was maybe just immaturity,” Hayes said.

“As it’s come out I think he’s just a quality run-on sprinter like Eagle Falls or Bel Sprinter.”
