Mo Farah has announced that he will run in the 1,500 metres at the Birmingham Grand Prix.

The 32-year-old, who is Olympic champion at 5,000 and 10,000m, will be aiming to break his own British 1,500m record at the event in June.

"The World Championships in Beijing is the main aim for this year. Birmingham will be good to work on my speed in a shorter early season race," Farah said.

"It will be good to step down to 1,500 metres and test myself over a shorter distance. Some of the best middle distance runners in the world will be in the field so I will have to be at my best to compete with them."

Farah, who is also a gold medallist in the 5,000 and 10,000m at the World and European Championships, set a two-mile indoor world record of eight minutes and 3.40 seconds at the Birmingham Indoor Grand Prix in February.
