British number one triathlete Helen Jenkins hopes to secure her 2012 Olympic qualification on Saturday on the London Games course.
Jenkins will qualify should she finish on the podium at Hyde Park or among the medals at the World Championship grand final in Beijing on 10 September.
The 2008 world champion has achieved successive third places at Hyde Park.
"If I can qualify this year, it gives me a year to prepare," the 27-year-old Welsh athlete said.
"There is an opportunity to qualify for the Olympics next year, but I'd be able to just to focus on competing at the Olympics and not worry about selection.
"So I'd ideally like to qualify this year."
Jodie Stimpson, Jodie Swallow, Liz Blatchford and Vicky Holland are Jenkins' main rivals to represent Team GB at their home Olympics.
Jenkins finished second in her previous two World Cup races in Madrid and Austria.
But she missed the series event in Hamburg last month to concentrate on training ahead of the first London 2012 qualifier.
Jenkins, who is sixth in the overall triathlon world rankings, insists Olympics redemption is her main aim as she aims to better her 21st placed finish at the 2008 Beijing Games.
"The aim of this year is qualifying for Olympics," said.
"So if I end up fifth, 10th or first in world championship series then it doesn't matter.
"I didn't get the best out of myself on that day in Beijing as I wasn't 100 percent going into the Olympics. But in 2012, I want to show what I can do.
"I learned a lot from going to Beijing and how to deal with the pressure of the event. I hope to take that experience on to London."
