EAST Devon runner Jo Pavey will make her return from injury in a top-class field in the adidas Women's 5k Challenge in London tomorrow.

The Exeter Harrier was forced to pull out of the 10,000m event at last month's European Championships because of a niggling toe injury.

But she will return to action in the 13th annual running of the Women's 5k Challenge.

World 10,000m champion Linet Masai will bid to keep the Hyde Park title in Kenyan hands after she was beaten to the win last year by just one second by teammate Vivian Cheruiyot, which ended four years of Ethiopian dominance.

"I am happy to be back at the Women's 5k Challenge," said Masai, who broke her 5,000m track PB at the Shanghai Diamond League meeting in May. "Last year I lost in a sprint finish but this time I will be stronger at the end."

Masai heads an elite field that also includes fellow Kenyan runner Sylvia Kibet, the world silver medallist, Ethiopia's former World cross-country champion Worknesh Kidane, Virgin London Marathon runner-up Inga Abitova of Russia, who was fourth last year, Polish record holder Lydia Chojecka, Lauren Fleshman of USA and Portuguese champion Dulce Felix.

Pavey heads the British challenge and she will be joined by former world junior 1,500m champion Stephanie Twell, who finished a creditable seventh in that event in Barcelona.

Former champion Sonia O'Sullivan will be one of a number of past elite runners and celebrities among the 15,000 club athletes, fun runners and charity fundraisers set to take part in the picturesque central London run.
