Percy Set For Sheema Prep Sir Percy is set to warm-up for the Dubai Sheema Classic in late March with a run four weeks earlier at Nad Al Sheba.Trainer Marcus Tregoning is eyeing the nine-furlong Jebel Hatta on March 1 before the Group One Sheema Classic over a mile and a half 30 days later, when he could clash with Breeders' Cup Turf hero Red Rocks.'He'll probably then have a break until Royal Ascot,' said the Lambourn-based handler.Sir Percy was restricted to just three runs this year. After finishing second to George Washington in the 2000 Guineas, he won the Vodafone Derby but was a disappointing seventh on his belated return in the Emirates Airline Champion Stakes at Newmarket in October.'After his well documented muscle problems after the Derby, we thought we had him right for the Champion Stakes, but it wasn't until two weeks after that race that he really sparkled again ? unfortunately by then there was nowhere to go,' Tregoning told the Racing Post.?
