Istabraq set for racecourse gallop Istabraq may have a racecourse gallop tomorrow, trainer Aidan O`Brien revealed tonight.'We want to take his preparation a step further by getting a racecourse gallop into him. But it all depends on the weather and the ground,' said the Ballydoyle trainer.'Wherever he goes he`ll do a lap of the track and perhaps jump a hurdle. Charlie Swan will ride him.'The triple Smurfit Champion Hurdle winner has just had the one race this season at Leopardstown in December when he narrowly defeated Bust Out.O`Brien has resisted the temptation to give the horse a competitive outing before his bid to win the Cheltenham showpiece for a record fourth time.Istabraq is 15-8 favourite with Coral for the race on Tuesday, March 12th.
