ATHLETICS/Sheffield Grand Prix: Sonia O'Sullivan admitted she will look to defend both her 5,000 and 10,000 metres titles at the European Championships in Munich in August.
Following an emphatic victory over American Marla Runyan in the 3,000 metres at the Norwich Union Classic at Don Valley Stadium, Sheffield, O'Sullivan confirmed she would double up.
She said: "I might as well try it. You've got to try it, but I have to get the 5,000 qualifying time."
O'Sullivan was taken aback by the nature of her triumph over Runyan, who had won when they last met in May.
"I always felt in control. I was surprised. I had run over 2k before I looked behind me and realised I would not have to save something and could just push on."
The Cobh runner was moderately pleased with her time of 8.44.02 in blustery conditions, but was more concerned to have regained the initiative with Runyan.
She said: "It was important to get one over on Marla. It gives me confidence for when I face Szabo and the others, as I am building up to the Europeans.
"But I need a good, hard race. I need to work on my speed and I need to win a duel down the home straight."
Runyan, who suffers from a degenerative eye disorder and is registered blind, was surprised by her time of 8.46.67 in such difficult conditions.
She said: "Considering the wind and that neither of us had much help, it's not bad. Anyway, tough conditions make you tough."
In the women's 800 metres Olympic and world champion Maria Mutola of Mozambique pipped Slovenia's Jolanda Ceplak after a battle down the home straight.
Britain' Kelly Holmes was back in fourth place.
Meanwhile, Britain's Dwain Chambers and Mark Lewis-Francis signalled a new world order is on the horizon as they left America's sprint king Maurice Greene trailing in their wake.
The duo both broke the 10 seconds barrier as Olympic and world 100 metres champion and world record holder Greene could only finish sixth to suffer his worst defeat in six years.
Chambers claimed his second victory over the Kansas Cannonball in the space of three days, winning in 9.95 seconds with 19-year-old Lewis-Francis second in 9.97, though the times were aided by an illegal wind.
But it is the significance of this result that could linger for the rest of the summer as the duo maintained the feelgood factor in British athletics following last week's European Cup triumph in France.
"We whooped their backsides and put on a good show," said Chambers, who had beaten Greene by just 0.01secs in Norway last Friday night, after spearheading a stunning clean sweep with Jason Gardener third in 10.11.
"I did not want to change anything from Oslo, just to go out and do that again. I could see Maurice had a bad start but I wasn't going to hang around for him.
"I have achieved one goal in beating Maurice and it is hard for him to have a Brit beating him.
"He could be jet-lagged and will come back again. But when he is back to form, I will be there to beat him again."
Lewis-Francis proved again that he will be a major threat.
"Beating Maurice is a bonus because I have idolised him for years," he said. His time equalled the mark he set at last year's World Championships in Edmonton, though that was also ruled out because of a faulty wind-gauge.
