Lee McConnell is praying her injury nightmare is finally behind her as she steps up her preparations for the Berlin World Championships in August.

McConnell's Olympic Games were put to a premature end last summer as she tore a quad muscle which forced her to pull out of the 4x400 relay heats in the Beijing Bird?s Nest.

But the 30-year-old, who has targeted the London 2012 Olympics as her final major event, insists she is in the shape of her life.

"I've had quite a hard two years with injuries," said McConnell. "I just want to try and actually be on the start line in physically good condition.

"Last year I tore a quad at completely the wrong time so this year I want to be there without any injuries.

"I've made improvements over the winter and hopefully those will show this season."
