Chalmers sets 100m freestyle PB, says best is yet to come

Dripping wet from his fastest 100m freestyle, Kyle Chalmers makes a stunning admission: he doesn't feel entirely world-class just yet.

The 20-year-old clocked 47.48 seconds in his pet event at the Australian titles in Adelaide on Monday night.

The time was 0.10 seconds quicker than his previous quickest, his gold-medal swim at the 2016 Olympics.

Chalmers now has the two fastest 100m freestyle times in the world this year – and he's nowhere near peak fitness.
