As Libby Trickett contemplates retirement, Jones showed she is the blonde bombshell to count on heading to London's 2012 Olympic Games with a dominant display at the Berlin World Cup meet over the weekend.

Jones added the 200m breaststroke world record yesterday to her 100m mark set just 24 hours earlier as she continued her stunning competitive comeback after skipping the Rome world championships in July.

Jones, 24, who won two Olympic golds and a silver in Beijing, said she was more confident in her ability after her restructured program this year. The Melbourne-based swimmer skipped the world titles to focus on beautician studies through the year and adopted a training program with more land activity.

The break from competition rejuvenated her mentally and physically as she aims to become a four-time Olympian in London 2012.

Jones won the 200m breaststroke in 2min 15.42sec to take more than a second off the previous record set by Canada's Annamay Pierse.

On Sunday, she took 0.72s off her own 100m world record.

Jones's world record was one of 10 on the second and final day of competition in Berlin, with the series tally of world records now a ridiculous 33 from just eight days of competition.

The end of the swimsuit debacle cannot come soon enough.

The successful return to racing is also positive for Trickett, as Jones shows true champions can take breaks and return as strong as ever.

Jones, who was also third in the 50m breaststroke, said, ''It's been a good weekend, I am just enjoying being fit and I am enjoying racing.

''No Australian has done four Olympics, but I have been pretty lucky as I started when I was 14.

''I started quite young and I still love the sport. It's still less than three years away, so in terms of training it's not that much time. My body knows what it has to do and there is not that much improvement I would need to do for it. It doesn't feel that far away at all.''
