Sanya Richards-Ross setting sights high for Birmingham

World 400m champion Sanya Richards-Ross is looking to use her appearance at the Birmingham Grand Prix to prepare for her World title defence in August.

The 26-year-old American lost the whole of the 2010 season to injury after taking gold in Berlin the year before.

After appearing in Birmingham on 10 July, she will travel to South Korea for the World Championships in August.
