Dibaba is keen to fine tune her fitness ahead of next month's Worlds

Tirunesh Dibaba will run in Saturday's 5,000m at the London Grand Prix ahead of the Berlin World Championships.

The Ethiopian, 24, made history at the Beijing Olympics last year when she became the first female athlete to win gold in both the 5,000m and 10,000m.

She said: "The London Grand Prix is important for me as a final test before the World Championships. I hope to give everyone a preview of Berlin."

Dibaba has only had one outing on the track so far this season.

She finished second behind Kenya's world cross country silver medallist, Linet Masai, in New York back in May.

That race followed a lay-off of six months over the winter, and next Saturday's race at Crystal Palace will be only the second time Dibaba has competed in London.

Her previous appearance came three years ago when she set a personal best that still stands of eight minutes 29.55 seconds to win the 3,000m.

Dibaba holds the world record for the 5,000m, having clocked 14:11.15 in Oslo last year.
