Commonwealth Games gold medallist Cody Simpson is returning to entertainment after a captivating four-year professional swimming career which led to him representing Australia.

After failing to make the Australian Olympic swimming team for the Paris Olympics, Simpson took to social media to tell his followers he could rest knowing he gave everything he had in the pool.

ABC Sport will be live blogging every day of the Paris Olympics from July 27 (Australian time).

Despite his Olympic dream coming to an end, Simpson did not say he was retiring from professional swimming.

“All you can do is everything you can to take what you’ve been given as far as you can take it,” he wrote.

“You owe yourself the honour of cultivating your talents with as much fervour and intensity as you can.

“The privilege of becoming what you’re capable of becoming.

“I left nothing to the unknown these past 4 years and I can now rest knowing I put my pedal to the floor every day and covered every other little detail to take this as far it could go and it sure went a hell of a ways.”
