Power feels Car hitting form Robbie Power has high hopes of a decent run from Chasing Cars in the John Smith's Topham Chase at Aintree on Friday. The jockey won the Grand National on Silver Birch in 2007 and can see the Jessica Harrington-trained nine-year-old putting up a good show in the two-mile-five-and-a-half-furlong handicap over the big fences. Chasing Cars may not have bothered the judge in either of his two starts this winter but Power believes the Supreme Leader gelding is a different horse in the spring. "He comes to himself this time of year in the spring and he seems in good form at home so I'm looking forward to him," he said.
