Jessica Fox will defend canoe slalom gold at Paris Olympics

Golden girl Jessica Fox will be back to defend her C1 crown in Paris, having already tested out the 2024 Olympic whitewater course en route to Tokyo.

Winning an emotional gold in the C1 as well as bronze in the K1 this week to go with a bronze and silver medal in that event from Rio and London, Fox is already the most successful female canoe slalom athlete of all-time.

But the 27-year-old said she's not done yet, committing to compete in the double in Paris in three years time.

"I was actually at the Paris Olympic course before coming to Tokyo, it was part of my preparation, because it is an Olympic venue and I wanted to see what it looked like, if there was similarities to Tokyo," Fox said.

"So it was good to actually get there and I'm definitely, definitely still hungry to keep going for another three years."

Born in France to a French mother Myriam Fox-Jerusalmi, a former Olympic medallist who is also her coach, Fox is at home in Europe, and will head there from Tokyo rather than back to Sydney.

With her father Richard Fox, also a multiple canoe slalom champion, back in Sydney working as an Olympics television commentator, Jessica shared her triumph with her mother.

"Both my parents have been hugely influential, I mean I wouldn't probably be in the sport if it wasn't for them," Fox said.

"Mum's just amazing - she's the most motivated, determined passionate woman I've ever met and inspires me every day."

Fox had earlier said she could empathise with American gymnastics great Simone Biles over the pressure she felt before her withdrawal from the all-around Tokyo Olympic final.

Like Fox, Biles is considered as the standout in her sport, even wearing an embroidered goat on her competition leotards, standing for Greatest Of All Time.

But the 24-year-old American made a shock exit from the team's event before pulling out of the all-around, citing mental health concerns.

Biles said it had been a "long Olympic process, a long year. We are just a little bit too stressed out. We should be out here having fun".

While Biles received an outpouring of support, she did cop some criticism on social media for not putting her team and country first.

Fox told of her own pressure going into the Olympics, where she was a raging favourite to win gold in both the K1 and the new C1 - and the heartbreak at falling short in her first event.

Her preparation was also affected with the whitewater venue in Sydney damaged by flooding, while she was unable to compete overseas for more than a year due to COVID-19.

With the stress taking its toll, she said she vomited before her gold medal run due to nerves, which is something she'd never done before.

With gymnastics always in the Olympic spotlight and Biles the face of the American team, Fox felt for the gymnast superstar.

"I can't imagine what Simone's going through," Fox told AAP.

"It's very tough to be doing this and I haven't really been watching the news and been on social media as much as normal.

"I've definitely felt that load and that pressure and there was a lot of relief at the finishing line.

"It was very taxing. I had to do a lot of mental work over the past 48 hours.

"It just shows that I have done the work over the last five years to get to this moment so I am just really proud of that."
