Britain's Commonwealth 1,500m champion Lisa Dobriskey has decided to go up a distance and compete in the 3,000m at the forthcoming AAA Championships.

She hopes it will help her training but does not expect to switch permanently.
"I normally do cross-country in the winter, but they've taken the 4K out of the World Cross-Country Championships," the Ashford runner told BBC Radio Kent.
"They've got an 8K instead which is too far for me. So I'm just doing it to remain competitive and see where I am."
Dobriskey's Commonwealth victory in Melbourne last year came after she shaved nearly two seconds off her personal best time.
