Adelaide: Three-time Olympic champion Libby Trickett has failed in her bid to qualify for next month`s world swimming championships.
Trickett, who had not competed since August 2009 after retiring, was seeking the remaining berth on Australia`s 4x100-meter freestyle relay team for the July 16-31 titles in Shanghai, China. Trickett, needing to win a swim-off in a time under 54.99 seconds Wednesday, came sixth in 55.68 at the South Australian Aquatic Centre.
Trickett, who won a relay gold at Athens in 2004 and individual and relay golds at Beijing in 2008, was not eligible for the Australian trials due to a requirement for her to undergo drug-testing before competing. She still hopes to compete at next year`s London Olympics.
