World champion Lauren Parker will take extra confidence into Tokyo 2020 after all-but booking a Paralympic debut with "the race of my career".
The Newcastle wheelchair athlete produced a career-best paratriathlon performance when it mattered, claiming her most prestigious prize with a dominant victory at the ITU World Triathlon Grand Final in Switzerland this week.
"It really is still sinking in," Parker told the Newcastle Herald while still overseas following her international success.
"I think overall I'm still on a high and feeling super happy with producing the race of my career."
The 30-year-old's showing in Lausanne, finishing ahead of US rival Kendall Gretsch, Germany's Christiane Reppe and fellow countrywoman Emily Tapp, comes 12 months out from the Games.
"With the large amount of points on offer at world champs I have more or less secured my place at the Paralympics next year in Tokyo, which is great to have done almost a year out from the event," she said.
"The event in Lausanne was a good rehearsal for the Paralympics with all the main contenders racing. I'll definitely take a lot of confidence from this win, which is great leading into next season."
Parker said "everything just clicked" during the 750 metre swim, 20 kilometre bike and 5km run.
"Even our changes in transition were the best we've ever done," she said.
Next up Parker lines up at a World Cup race in Spain on Sunday before contesting her first half-ironman event as a paratriathlete at the Middle East 70.3 Championships in Bahrain in December.
The former triathlete suffered life-changing injuries in a freak training accident in 2017. She has since undergone spinal surgeries, including earlier this year.
"Health wise I'm in good shape," she said.
"It was good to have a race preparation uninterrupted by medical issues or surgery."
