On the Rails ... Horse Power.

Byline: MIKE TORPEY

BOOKMAKER Stan James has installed the 2008 Cheltenham Gold Cup winner Denman at 14-1 to win both the blue rib and event and the John Smith's Grand National in 2009.

After his impressive victory at Cheltenham on New Year's Day, Calgary Bay has continued to be backed and is now 10-1 (from 12) for the Arkle at the Cheltenham Festival despite his trainer Henrietta Knight's uncertainty as to which route the six-year-old may take.

There has also been support for Cooldine who is now 12-1 (from 14) for the RSA Chase and Walkon 8-1 (from 9) in the Triumph Hurdle.

MARODIMA could still take his chance in the Victor Chandler Chase at Ascot despite being denied a prep run when Sandown was abandoned last Saturday.

Trainer Rebecca Curtis was keen to get an outing into the six-year-old before the Grade One feature on January 17, for which he is a 50-1 shot with the sponsors.

"We would like to run him there but it's a big ask without a run beforehand," said the Newport-based handler. "I'd say he'd probably run, but I wouldn't be 100% happy."

HENRY DE BROMHEAD is hoping a return to form for his string can see stable star Sizing Europe bounce back to his brilliant best in the Toshiba Irish Champion Hurdle at Leopardstown on January 25.

The seven-year-old was a hugely impressive winner of the Grade One contest 12 months ago but faded tamely into fifth place behind Sublimity in the December Festival Hurdle.
