Ahead of the final leg of the 2011 series, the Cathay Pacific Hong Kong Sprint on Sunday week, organisers of the Global Sprint Challenge have expanded the 2012 edition to include the Golden Shaheen in Dubai. The 10th race to join the Global Sprint Challenge, the Golden Shaheen on Tapeta will be the only leg not run on turf during the series stretching from the Lightning Stakes in Melbourne in February to the Hong Kong Sprint in December. With retired compatriate Star Witness, Australia's champion mare Black Caviar leads the points score for the 2011 series, with two wins at home in Melbourne making her the only multiple winner for the year, but any of Rocket Man, Society Rock, Curren Chan or even Bated Breath could wind up on top of the table with an away win at Sha Tin. And for any title or trophy to be awarded a minimum number of points is required. One positive change to the series will be a softening of the criteria for winning a US$1 million bonus. Previously, a horse was required to win three Group One legs outside its home jurisdiction to earn the bonus, and no horse has claimed the prize in the seven-year history of the series. That requirement will be less demanding next year, with wins in any three Group One legs demanded, regardless of where the races are run and the bonus will be divided between the owner (75 per cent) and the trainer (25 per cent).
