Off Track ..... Colin Jackson thinks Robles is unstoppable

China's hope of taking one of the most coveted athletics golds is fading fast as Cuban 110m hurdler Dayron Robles looks unstoppable in the Beijing Olympic Games, former world record holder Colin Jackson of Britain said on Monday.

A race between Robles and hometown favorite Liu Xiang was expected to be one of the best match-ups of the Olympics, but Robles, who broke Liu's world record in June, has run away from the pack while Liu has been inconsistent and has been struggling with minor injuries, Jackson said.

"I'll always look for Robles, with the times he's run this year, as consistent as he's been, as fluent as he's been," Jackson said. "I'd definitely call him the winner."
