The world's most travelled racehorse, trained in Newmarket, has been retired after his failed bid to win Australia's richest race at the fifth attempt.

Red Cadeaux suffered a serious leg injury and failed to finish the Melbourne Cup overnight.

His trainer, Ed Dunlop, said his injury wasn't life threatening but added that he would not race again.
