Olympic champion Kyle Chalmers and singer Cody Simpson were listed side-by-side in the promotional billing for a documentary series series ahead of Australia’s Olympic swimming trials.

On the result lists for the 100-meter freestyle preliminaries Tuesday, the names were a long way apart.

The 22-year-old Chalmers led qualifying for the night finals in the 100 free with a time of 48.58 seconds. Chalmers is coming off a win in the 200 freestyle on the weekend, his best hit out since surgery on his left shoulder last November.

Simpson, who has put his music career on hold while concentrating on swimming at his first Olympic trials, finished 23rd in the rankings among the 92 swimmers in the heats. Still, his time of 50.22 was a personal best. And his preferred event — the 100 butterfly — is two days away.
