When the doors of the Edenvale Dojo swing open, the rhythmic sound of focused breath, controlled power, and disciplined movement fills the room. At the centre of it all is Marinda Roetz — South Africa’s 50kg Kumite sensation, a top-ranked African karateka, and one of the world’s best, currently sitting among the top 70 athletes globally in her division.
This November, Roetz will represent South Africa at the World Karate Championships in Egypt, marking a new milestone not just in her own journey, but for South African karate as a whole. Before the Championships, she’s spending six intense weeks in Cairo at an elite training camp — a rare invitation to train alongside some of the sport’s finest.
“I’m going to stay there for about six to seven weeks, training with one of Egypt’s main coaches,” she explains, her voice a mix of calm focus and excitement. “It’s only through the Lord that I got this opportunity, and I’m so grateful. Training with the best of the best will help me see that I am capable. I feel ready — mentally and physically — like I am already a world champion. All that’s left is the gold medal.”
A Family Built on Karate
For the Roetz family, karate isn’t just a sport — it’s a way of life. Marinda began training at the age of four, growing up in a home where discipline, humility, and strength were part of everyday lessons. Her father, Sensei Michael Roetz, holds a 7th Dan and runs the family’s dojo in Edenvale, where Marinda not only trains but also teaches.
“My dad has always been my inspiration,” she says. “His will, his passion, and his love for what he does — that’s what keeps me going. Inside the dojo, he’s my sensei. Outside, he’s my biggest supporter.”
Her mother, while no longer teaching, still plays a key national role as Secretary of Karate South Africa, helping steer the sport’s development from behind the scenes. “She might not be on the mat anymore,” Marinda smiles, “but she’s definitely still in the fight.”
Together, the family forms one of South Africa’s most respected karate dynasties — with Marinda carrying forward the legacy, now adding her own global ambitions to it.
Strength Forged in Resilience
While this won’t be her first World Championships appearance, Roetz admits that this one feels different.
“In the past, I struggled a lot with self-worth and believing that I belonged on that level,” she reflects. “But I’ve overcome that. I’m stronger now — mentally and emotionally — and I know what I’m capable of.”
Qualifying for the 2025 World Championships was no small feat. The new system, she explains, was far tougher than before:
“This year they introduced regional qualifications on top of national rankings. Less than 50 athletes in the world made the final cut. So just getting there already means you’re among the very best.”
Training Among Giants
Egypt is widely regarded as one of the powerhouses of world karate — home to elite athletes, advanced techniques, and a culture that lives and breathes the sport. For Roetz, the Cairo camp is not just preparation; it’s a rare chance to sharpen her edge.
“I’ve done some online training with their team before, and it boosted my confidence,” she explains. “Our dojo’s level in South Africa is right up there — but this camp will add intensity, speed, and tactical sharpness. I’m ready to absorb everything I can and bring that knowledge home.”
Her Defining Moment
When asked about her most memorable career moment, Roetz doesn’t hesitate to recall a competition in Croatia in 2022.
“I was fighting for third place and behind on points with just a few seconds left. Somehow, instinct just took over — I landed a technique perfectly, and the referee’s hand went up for the point. That third-place finish felt like winning gold. I had lost there twice before, but that time I made it. It was pure adrenaline — one of the best moments of my life.”
It’s that same resilience that now fuels her journey to Cairo and beyond — a mix of faith, fight, and family.
Teaching, Competing, Inspiring
Balancing her dual role as athlete and instructor, Roetz finds meaning in giving back to the next generation. “Being both a competitor and a sensei keeps me grounded,” she says. “You’re always learning — from your students, your peers, and your own setbacks.”
She speaks passionately about wanting her journey to inspire others:
“Even if I don’t bring back a medal, I want to bring back hope — to show South Africans that it’s possible, that you can reach the world stage if you believe and put in the work.”
A Glimpse Beyond the Dojo
Away from competition, Marinda’s energy doesn’t fade — it just shifts. Her playlists include Shakira’s “Waka Waka”, a personal pre-fight anthem that “brings the vibe,” she laughs. She cross-trains with Muay Thai, dreams of learning ballet, and swears by her quirky recovery snack — muesli mixed with peanut butter and honey.
When asked what karate has taught her most, she answers with quiet conviction:
“To be fearless. To face my fears. To stand strong, be brave, and be courageous.”
A Champion in Spirit
Watching Marinda Roetz train under the watchful eye of her father, it’s easy to see why her Sport South Africa visitors dubbed her the “Pocket Rocket.” Her movements are explosive yet composed, her focus unwavering. But beyond the speed and skill lies something deeper — a sense of purpose rooted in gratitude and belief.
As she boards her flight to Cairo for six weeks of world-class training before the 2025 World Championships, South Africa will be watching — and cheering — for the young woman who embodies what it means to fight with heart, heritage, and humility.
“I feel like I’m a world champion already,” she says, smiling. “Now it’s time to go prove it.”
