( CNN ) -- It happened at Royal Ascot . Now it has happened again at York . Any doubts over whether Frankel , rated the best racehorse in the world , would prove himself the master of the 10 furlong distance , as he has over eight furlongs , were dispelled Wednesday . Frankel made one of the toughest fields he has ever faced look pedestrian , defeating Fahrr and St Nicholas Abbey by a widening seven lengths to win the Juddmonte International at the racecourse in the north of England and extend his unbeaten record to 13 . Frankel certainly can not be said to suffer from triskaidekaphobia , a fear of the number 13 . The first of his victories came on Friday 13th in August 2010 . That half-length victory over Nathaniel is the closest anyone has come to the great colt since . His biggest winning margin has been -- you guessed it -- 13 lengths . The annual York meeting had long been turned into a one-horse race ever since Frankel 's trainer , Henry Cecil , targeted the Juddmonte for Frankel 's debut over the one mile and a quarter ( 2,000m ) trip . On Wednesday , fans lined every inch of rail from the parade ring to the starting gates to get a glimpse of the horse that may possibly represent the culmination of 300 years of selective breeding to create the ultimate equine athlete . Superstar swagger . With the swagger of a superstar , Frankel emerged from the saddling area to a sea of pink and green ( his owner , Khalid Abdullah 's racing colors ) . Accompanied into the parade ring by a phalanx of policemen , the great colt looked far more relaxed than either his trainer or his jockey , Tom Queally . The most interesting and compelling race of Frankel 's career to date was given more piquancy by the presence of Cecil , who was returning to the racetrack for the first time in months following ongoing treatment for cancer . The Juddmonte International is something of a graveyard of champions ; 11 out of 17 horses that have started as odds-on favorites here have been turned over . Most famous of these was Brigadier Gerard . In the summer of 1972 , Brigadier Gerard swept aside all comers in the same insouciant manner that Frankel does today . But it was in this race 40 years ago that he suffered the only defeat of his career . In a massive upset , the 1972 Epsom Derby winner Roberto ran the race of his life to beat Brigadier Gerard by three lengths , smashing the course record in the process . Frankel , starting the race at 10-1 on , suffered no such upset . Despite losing a couple of lengths at the start , there were never any signs of panic from his jockey , a virtually motionless Queally . Tactical ploy . Rival trainer Aiden O'Brien was determined , as ever , to halt Frankel 's seemingly inexorable progress toward perfection , making the task something of a tactical puzzle by his use of pacemakers to assist St Nicholas Abbey . But an unruffled Frankel was content to settle towards the back of the field for the early part of the race , and all that remained was for Queally to pull the pin in his customary fashion with two furlongs to go . Frankel duly galloped into uncharted territory and into the history books . Frankel has now surpassed the mark set by Rock of Gibraltar for consecutive Group One wins with eight . The view of Frankel receding into the distance is one that the likes of top jockeys Frankie Dettori and Joseph O'Brien are already familiar with . It is a sight that racing fans will have to accustom themselves to now that Frankel 's career looks to be following its inevitable trajectory toward the breeding shed . With just one race left on his card -- the Qipco Champions Day at Royal Ascot in October -- the finest athlete to grace this sport is in the home stretch of his long gallop into immortality .
