Jessica Fox’s name is etched into Australian sporting history, not only for the medals she has won but for the consistency, control and humility she has carried across four Olympic cycles. In late 2024, however, attention briefly shifted away from podiums and paddles to a deeply personal chapter of her life, after Australian media revealed she had quietly ended a long-term relationship earlier in the year.
The story was not one of scandal or controversy. Instead, it resonated because of timing. Fox had spoken openly about wanting to start a family. Then came a private separation. Months later, she delivered one of the greatest Olympic performances by an Australian athlete in Paris.
This article brings together all available information from Australian sports reporting and the details you provided, presenting the full picture what happened, what was said, and why the story mattered to so many Australians.
A Career Built Over Decades, Not Moments
By the time she arrived in Paris in 2024, Jessica Fox was already one of the most decorated canoe slalom athletes in history. Across four Olympic Games, she accumulated three gold medals, one silver and two bronze, alongside 22 world championship medals, a tally unmatched in her sport.
Her achievements are the result of relentless preparation, long training blocks, and a lifestyle shaped by international competition. Fox has spent years dividing her time between Australia and Europe, chasing marginal gains in a discipline where fractions of a second decide outcomes.
That same lifestyle also shaped her personal relationships.
Meeting Mathieu Biazizzo on the International Circuit
Jessica Fox met Mathieu Biazizzo through the world she knew best elite canoe slalom. Biazizzo, now 33, is a French kayaker and canoeist who competed at the highest international level for more than a decade.
His career included a standout moment in 2016, when he won the K1 world championship and later claimed the overall World Cup title that same year. He competed for France at numerous world championships and was regarded as one of the most technically skilled paddlers of his generation.
The pair began their relationship around 2015, after meeting on the World Cup circuit. From the outset, their connection was shaped by shared routines: early mornings, training sessions, recovery schedules and the constant movement between countries.
A Relationship Kept Away From the Spotlight
Despite Fox’s rising profile in Australia, the relationship remained intentionally private. There were no coordinated media appearances, no joint interviews and little social media exposure.
Australian sports coverage over the years referenced Biazizzo only sparingly, usually in the context of Fox’s training environment or international travel. The absence of public commentary was consistent with Fox’s broader approach to fame focused on performance rather than personal narrative.
When Fox did speak about her partner, she framed the relationship through the lens of understanding and balance, not celebrity.
Sharing Life With Another Elite Athlete
In interviews conducted in 2023, Fox offered rare insight into what it meant to share her life with another high-performance athlete.
She spoke about the dynamic of training together, acknowledging that competition existed even within the relationship. She described it as natural rather than problematic a by-product of two driven people pushing themselves daily.
She also reflected on the comfort of having a partner who understood fatigue, pressure and the mental demands of elite sport. Simple routines, like going to bed early together, were framed as shared discipline rather than sacrifice.
These reflections were calm, grounded and forward-looking.
Conversations About Motherhood and the Future
It was during these same interviews that Fox spoke about starting a family.
She acknowledged that motherhood was something she wanted, and that conversations about having a baby were approaching. She discussed the possibility of stepping away from competition, having a child, and returning a path increasingly explored by elite female athletes, though still filled with uncertainty.
Fox did not frame motherhood as a deadline or demand. Instead, she spoke about it as an evolving decision shaped by health, timing and opportunity.
At the time, her comments were seen as thoughtful reflections from an athlete entering a new stage of life.
The Quiet Separation in May 2024
According to Australian sports reporting, including Yahoo Sport Australia and later The Daily Telegraph, Jessica Fox and Mathieu Biazizzo separated in May 2024.
The split occurred quietly and without public statements from either party. It did not become widely known until December 2024, when Australian outlets reported the separation and contextualised it within Fox’s career-best year.
The delayed public revelation explains why the story resurfaced months after the relationship ended.
Why the Relationship Ended
Australian reporting consistently pointed to long-distance strain as the central factor.
Fox divides her time between Australia and Europe for training and competition, while Biazizzo is based in France. After nearly nine years of living across continents, sources described the pair as having grown apart.
There were no reports of conflict, infidelity or third-party involvement. The separation was framed as the natural conclusion of a relationship shaped by demanding schedules and geographical distance.
Importantly, neither Fox nor Biazizzo commented publicly after the split became known.
Why Australian Media Used the Word “Heartbreaking”
When the story emerged publicly in December 2024, several Australian headlines described it as “heartbreaking”.
The term was not used to suggest drama or distress. Instead, it reflected the emotional contrast between:
- Fox’s earlier comments about wanting to start a family
- The end of a nine-year relationship before those plans progressed
- Her subsequent triumph at the Paris Olympics
The framing acknowledged the human reality that major personal decisions do not always align neatly with professional milestones.
Paris Olympics: Personal Change, Professional Peak
Despite the personal shift earlier in the year, Fox arrived in Paris in exceptional form.
She won gold in both K1 and C1, completing the elusive K1 title she had chased across four Olympic campaigns and defending her C1 crown. Her performances were controlled, decisive and free of visible distraction.
She was also chosen as Australia’s flag bearer, an honour that reflected her standing within the sporting community as much as her medal count.
Throughout the Games, Fox spoke only about preparation, performance and gratitude. Her private life remained separate from her public role.
A Surge in Profile After Paris
Following the Olympics, Fox’s profile rose sharply.
She signed with L’Oréal Paris, joined Channel 9 coverage across breakfast television and major sporting events, and appeared regularly in Australian media throughout the second half of 2024.
She was also named to the 2024 Forbes 30 Under 30 list, alongside other high-profile Australian athletes, recognising both her sporting achievements and broader influence.
These developments unfolded after her separation, highlighting how her career momentum continued unabated.
Family, Fame and the Fox Sisters
The Paris Games also cemented the Fox family’s place in Australian sporting culture.
Jessica shared the spotlight with her younger sister Noemie Fox, who won gold in kayak cross in her Olympic debut. Their shared success became one of the defining stories of the Games.
Later in 2024, the sisters jointly received Sport Australia’s Don Award, recognising their collective impact on Australian sport.
At public events, Noemie was seen attending with her partner, French paddler Titouan Dupras, a detail noted in coverage but never framed as comparison or commentary on Jessica’s private life.
Clearing the Record on Rumours and Scandals
Despite occasional speculation, Australian sports media has been consistent:
There are no scandals associated with Jessica Fox.
There have been:
- No misconduct allegations
- No disputes involving her former partner
- No behavioural or integrity concerns
- No public fallout following the breakup
The separation was handled privately and respectfully, and Fox’s reputation remains exceptionally strong.
Motivation, Longevity and What Comes Next
At 30, Fox has made it clear she is not finished.
She has publicly committed to the 2025 World Championships in Penrith, scheduled for October, describing the event in her hometown as a major source of motivation.
Beyond that, she is focused on the 2028 Los Angeles Olympics, with the possibility of extending her career even further depending on health and motivation.
Fox has repeatedly stated that enjoyment, hunger to train and personal drive not age will determine when she steps away from competition.
Current Relationship Status
As of the most recent Australian reporting:
- Jessica Fox has not confirmed a new partner
- No credible outlet has identified a new relationship
- She continues to keep her personal life private
Media attention has largely shifted back to her sporting ambitions and leadership role.
A Story About Timing, Not Turmoil
The public response to Fox’s relationship change reflects something deeper than curiosity. It speaks to how Australians relate to stories where success and uncertainty coexist.
Fox’s separation did not derail her career. Nor did her Olympic triumph erase the reality of personal change. Both unfolded side by side.
What remains constant is her control over her narrative choosing what to share, what to protect, and when to speak.
