Nicky Henderson could be too busy to attend the Spring Racing Carnival himself but his horse Forgotten Voice is being prepared for the long journey. While October and November represent the final major stages of the global Flat season, for Henderson the work will only just be starting for the defence of his British jumps title.

Forgotten Voice was moved by owner Paul Roy from Jeremy Noseda in order to explore the possibility of running over hurdles, and this time just over a year ago he was winning an event at Market Rasen, a country track in deepest Lincolnshire, under National Hunt legend Tony McCoy.

However, a preference for faster ground restricted his appearances in the wet British winter and Forgotten Voice returned to Royal Ascot in June to collect the Wolferton Stakes (2000m) under Johnny Murtagh - four years after landing a gamble in the Royal Hunt Cup for Noseda and the same pilot.

He was next seen at Glorious Goodwood and struck again, this time over 2400 metres in the Group 3 Glorious Stakes.

While Henderson should be plotting campaigns for his returning hurdlers and chasers, the must successful trainer in the history of the Cheltenham Festival is considering his Carnival options.

Forgotten Voice has been allotted 53kg in the weights for the BMW Caulfield Cup and it is an option for him ahead of the Emirates Melbourne Cup.

"We are preparing the paperwork for quarantine and we're having serious discussions about going," Henderson said.

"Johny and I were discussing things and we felt that there wasn't a lot left for him in England.

"He was once a miler but we've taught him to race differently. Johnny thought he felt better over a mile and a half at Goodwood than over a mile and a quarter at Ascot."

Murtagh has the Melbourne-bound Royal Diamond (55kg for Caulfield) in his own care as jockey-turned-trainer and Henderson is likely to have to search for his own rider.

Perhaps the 62-year-old will dig out some of his old contacts, as while working for stockbrokers Cazenove back in the late 60s, he rode trackwork at Randwick and recalls steering home a winner at the Bong Bong Picnics.

"He’s in the Caulfield Cup and the Melbourne Cup and you can do both," he said.

Henderson may end up clashing with Willie Mullins in rather different surroundings to a chilly Cheltenham in March.

Mullins, the dominant force in Irish jumping, intends for Simenon to travel.

While he has been given 54kg for the Caulfield Cup, his trainer has also suggested one of October's other lead-up races like the Herbert Power, Geelong Cup or the Moonee Valley Cup could be his gelding's route to certain qualification for Flemington.

Simenon was second to Estimate in the Gold Cup (4000m) before running Ahzeemah even closer in the Lonsdale Cup (3300m) at York.

"We're looking to run him somewhere in Australia before the Melbourne Cup," Mullins said.
