Amelia’s La Bout has run her last race and will be retired to stud.

Trainer Simon Miller and connections announced the decision to end her racing career after she ran 25 lengths last to Classic Pro at Belmont on Saturday.

It was the daughter of Hinchinbrook’s first official return to the race track since she sustained serious leg injuries in a paddock accident earlier this year.

Following a superb 1½ length win on debut at Ascot in March, Amelia’s La Bout suffered a lacerated hock and lacerated fetlock that required surgery.

Miller said Amelia’s La Bout’s failure on her return was too bad to be true and confirmed she had failed to overcome her injuries.

“Once you do damage to the fetlock there is a danger of arthritis setting in and that’s what the x-rays revealed,” Miller said.

“The vets couldn’t believe how aggressive the arthritis was and how it developed so quickly.

“Her work and trials were okay, but you are never sure until they are put under race pressure.

“She was travelling okay on Saturday, but when she was asked for an effort she didn’t respond.

“It’s disappointing, but the right call has been made.”

Meanwhile Miller said he is optimistic Oliver’s Travels can rebound and get his campaign back on track in Saturday’s $100,000 Listed Idyllic Prince Stakes (1300m).

Miller was left scratching his head when in a rare failure Oliver’s Travels beat just one runner home at his first-up run in last fortnight’s Listed Belmont Newmarket (1200m).

“I’ve poured the work into him,” Miller said.

“I might have gone soft on him leading to his first race.

“He ran through the line strongly at track work this morning (Tuesday).

“He is ready to go.”
