Athletics: Olympic champ Pearson back in training

Australia's Olympic sprint hurdles champion Sally Pearson said Thursday she was back in training and chomping at the bit after battling to overcome a hamstring injury.

The 100m hurdles London gold medallist missed the Australian track season because of the torn hamstring but is now hard at work again.

"Everything's looking up," Pearson told reporters.

"I started hurdling on Monday, which is probably almost eight months since I competed at the Olympics.

"It's the longest time I've had off hurdling but at the same time I think it's going to work well for me when I go overseas."

Pearson, 26, said her injury break had helped her increase her training load ahead of the European track season and the August 10-18 world championships in Moscow.

"We weren't planning on having a huge hurdling conditioning but because of the injury I've had to stop competition in Australia and move on to my fitness training," she said.

"It's a bit more confidence for me to know that I'm going to be hurdling for a bit more longer than I was going to be."
