Despite ten years of trying, Australian swim star Kyle Chalmers is still in pursuit of the perfect race.
The Olympic gold medallist secured his spot at this year's Commonwealth Games by taking the men's 100m freestyle on Thursday night at Australia's swimming trials.
After qualifying fifth, Chalmers fended off a challenge from Finn Southam to touch in 47.59 seconds at Sydney Olympic Park.
Southam trailed by 0.3 seconds to finish runner-up, with Kai Taylor third (48.21).
The 27-year-old Chalmers had set a 100m butterfly personal best of 51.04 seconds earlier in the week, but pulled out of the final.
Inspired by 32-year-old Cameron McEvoy's newly-claimed 50m freestyle world record, Chalmers was adamant he could reach another level.
Chalmers will also compete in Saturday's 50m butterfly event.
