Ian Thorpe has said that he has "no regrets" about his failed attempt to qualify for the 2012 Olympic Games.
The five-time Olympic champion came out of retirement last year in a bid to compete in London but will instead watch from the sidelines.
Despite failing to qualify, Thorpe, who has also won 11 world titles and 10 Commonwealth Games gold medals, said that he still might enter the pool in 2014 at the World Championships in Barcelona.
"Compared to how I have raced before and how I have competed, the success that I have had, this does look like doom compared to it," said the 29-year-old. "I'm glad that I was willing to put myself out there. I don't regret giving this a go.
"I think now I'll probably take a few days off and enjoy the competition and then sit down with a few people and work out what is next, work out what the next preparation will be and what competition will be next.
"I'm still swimming. When I started this I wanted to get back in the pool, I wanted to race and I wanted to go to the Olympics. I still want to do all of those things. I've missed out on a huge goal but the desire is still there."
Thorpe, who quit swimming in 2006, won three gold medals at the 2000 Games in Sydney and two in in Athens four years later.
