4 July 2012 - London, UK - Just in time Tirunesh Dibaba is back at her best. Four years after she wrote Olympic history in Beijing by becoming the first woman to take both long distance titles at the Games she defended her 10,000m gold medal. And by doing so she has again achieved something unique: Still only 26 years old the Ethiopian is the only woman in history who has won the 25 lap race at two Olympic Games in a row. And she may do even better next week in London, if Ethiopian officials decide to pick her for the 5000 metres as well.
