Consistency over talent: Bridget Theunissen prepares for Ironman world stage

Bridget Theunissen, a rising star in the South African triathlon circuit, has firmly established herself as one of the country’s top-ranked female athletes. At 25, she has become known for her remarkable versatility, excelling in both traditional road triathlons and off-road X-Terra formats.

Earlier this year, Theunissen claimed the women’s title at the 2026 Auto&General Xtri National Championships at Steyn City. Despite her current success, her journey into the sport was more about family than early ambition.

"So basically, how I became a triathlete was definitely through my family," Theunissen told Eyewitness News. "When my brother was younger, he used to do quite a lot of mountain biking and swimming, and I just went and tagged along anyway because I didn't want to be left at home by myself."

Her introduction to competitive racing began at the age of eight with a "mud man" off-road cross triathlon.

"I was extremely uncompetitive. I don't think I had a competitive bone in my body, so I pretty much came last," she recalled. "In all the events that I went to, my brother was winning, and I was literally the 'sweeper.'"

The turning point came at age 15 when she qualified for her first World Championships in Canada in 2015. After finishing third, her motivation surged. However, the transition to road racing at 16 proved difficult, leaving her "very far behind" in her initial events.

Theunissen—who secured a silver medal at the 2025 Africa Triathlon Championships and finished 30th at the Ironman 70.3 World Championships—attributes her trajectory to persistence rather than raw gift.

"I may not be necessarily the most talented, but I think my consistency has gotten me to where I am today. I've never really stopped training; I've just kept at it and kept chipping away."

Looking ahead, she is currently preparing for a Half-Ironman in Europe on May 10, followed by an Ironman Pro Series 70.3 race in France. These events serve as vital preparation for the 2026 World Championships in Nice, France, on September 12.

Beyond the podium, Theunissen remains committed to her community. In 2024, she organised the "Splash Tri Dash" in eManzimtoti, a Super League-style race that doubled as a fundraiser for local charities, including Operation Bobbi Bear, the SPCA, and Jona Vaughan Home.

"My mom works very closely with these organisations... that is why we decided to give back," she said. "As soon as I find the time, I will for sure look into [organising it] again."
