It is now two years since Istabraq won his third Champion Hurdle, since Tony McCoy and Edredon Bleu got the better of a titanic battle with Direct Route to win the Queen Mother Champion Chase and since Looks Like Trouble powered away from Florida Pearl in the Gold Cup. It seems like 10 years and God, has the racing world missed the buzz. The roar of the crowd, the manic magic of the betting ring, the examination of nerve, the strain of emotions: over three days and 20 races, the best horses Britain, Ireland and France can offer, all at the peak of their form, will try their hearts out as owners and trainers hear the beat of their own quicken beyond the medically recommended rate.
