The former Commonwealth bronze-medallist is making a remarkable comeback from an a long series of injuries which have ruined her track career for the last three years.

However, Fraser, 31, ran a solid 400m victory in Irvine, California, at the weekend.

The Croydon Harrier ran 51.49 seconds – quick enough for second place in last year’s UK rankings.

Qualifying for selection at the Team GB trials in July remains Fraser’s top priority, and she intends to arrive in Manchester in mint condition.

Fraser has attracted the attention of top US promoters after winning over the distance on two successive Saturdays following a spell of warm weather training in California – her first 400m race for three years saw her claim victory with a modest time of 52.63sec in San Diego.

According to coach Ayo Falola, Fraser is delighted with her progress but agrees, after seven races in a five weeks period, a rest from competition is now necessary.

“She’s run so well on her comeback, there have been invites for her to stay in the US and race in a couple of Grand Prix meetings,” said Falola who will fly home with his star athlete on Tuesday.

Falola, explaining the rejection of what would have been money-spinning pay days on the US circuit, said: “We’re shutting down on racing from now until June.

“It was always the plan to concentrate on training throughout May and we’re happy with the way things have gone.”

Four years ago, Fraser trained with Cathy Freeman – the eventual Olympic champion in Sydney – and the benefit of the experience shone through, even if fellow Briton Katharine Merry robbed her of a podium place.

And Falola said: “Donna’s fitter now than when she was in the Olympic year four years ago.”
