Meet Matej: Balancing the IB with an IRONMAN 70.3

For Year 13 learner Matej, setting an ambitious goal has never been about simply reaching the finish line. It is about finding the next challenge, understanding what it will take to achieve it, and learning along the way.

After seven years competing in sprint canoeing at the highest level, Matej felt he had achieved what he wanted from the sport. Rather than stepping away from competition altogether, he decided it was time to start a new chapter, one that would push him even further.

That next challenge was an IRONMAN 70.3: a 1.9km swim, 90km cycle and 21.1km run. Over the summer, Matej completed the race in Krakow, Poland, in 5 hours, 47 minutes and 29 seconds, becoming the youngest Slovak athlete to complete an IRONMAN 70.3.

And he did it while studying for the IB Diploma Programme.

Finding a new challenge

 

The idea began after Matej and his friends competed in the World Quadrathlon Championships, combining triathlon with canoeing. Enjoying the experience sparked a new ambition: could he complete an IRONMAN 70.3?

The scale of the challenge meant preparing for almost ten months, with training often taking place before and after school. At his peak, Matej was training up to 12 times a week across swimming, cycling and running.

Balancing this with the demands of the IB was not always straightforward.

“In terms of balance, there were weeks where I was able to train 12 times a week, and sometimes there were weeks where I had to simply prioritise school and barely managed to do three sessions,” says Matej.

Rather than viewing this as a failure to maintain a perfect routine, Matej saw it as part of learning how to manage competing priorities.

It is a mindset that reflects his approach to both sport and learning: setting realistic goals, working towards them consistently and understanding that progress takes time.

“From my experience, consistency always beats talent,” he says. “Personally, I think that my main mental strength is that I understand the importance of patience and long-term planning.”

Turning challenges into opportunities

 

The journey was not without setbacks.

One of Matej’s biggest practical challenges was cycling. During his first year in Singapore, his accommodation did not allow him to keep a bike, meaning he had to rent one. This limited his cycling training during the school year, although he was able to make up for it during the summer in his home country.

In the end, cycling ultimately became the discipline he was most proud of on race day.

He also suffered a serious back injury at the beginning of February, setting back much of his running progress.

Rather than allowing these setbacks to derail his goal, Matej used the experience to reassess and adapt.

“I always try to replace the word ‘challenge’ with the word ‘opportunity’,” he says. “Seems like it’s working.”

His experience also reinforced how important sport is to his overall wellbeing. During his recovery, he realised just how much he valued movement and physical activity, not only as a competitive pursuit but as an important part of his life.

 

Where sport and learning meet

 

For Matej, being an athlete and being an IB learner are not separate parts of his life. In many ways, each strengthens the other.

His interest in mathematics even found its way directly into his Ironman preparation.

While cycling, Matej noticed a physiological phenomenon known as cardiac drift, where heart rate gradually increases during prolonged exercise. He began wondering whether he could use mathematics to determine an optimum fluid intake that would minimise this effect.

The idea became the basis for his Mathematics Internal Assessment.

“Using mathematics I created something I can genuinely use to boost my physical performance, and hopefully academic as well,” he says.

This is a great example of the kind of learning that happens when academic curiosity connects with a learner’s passions and interests beyond the classroom.

Matej believes his varied interests, from mathematics competitions to canoeing and now triathlon, have helped him become a more well-rounded person.

“I believe being a well-rounded person eventually complements both my sports and academics,” he says. “In sports, you can develop a discipline that you can then practise in school, such as time management.”

Creating space to train at Nexus

 

For Matej, having access to the right support and facilities at school made it easier to fit his training around the demands of the IB. Through the Nexus Athlete Development Programme, he trained with the Nexus swimming team under Coach Dhill and attended morning gym sessions with Mr Carter.

“Nexus’ Athlete Development Programme was a key part of my Ironman journey,” says Matej. “Having the opportunity to train with the Nexus swimming team under Coach Dhill or having access to the morning gym sessions with Mr Carter helped me to create a consistent training schedule.”

Having these facilities on campus also saved Matej valuable time. Compared with sprint canoeing, where he previously spent an additional hour each day travelling by public transport to training, he could use that time to study, recover or catch up with friends.

For Coach Dhill, it is not simply Matej’s ability that stands out, but his maturity and self-motivation.

“It’s rare to see an athlete at this stage and age where they just come to practice knowing what they want out of themselves,” he says. “He’s definitely driven.”

Coach Dhill also sees the experience Matej gained through seven years of competitive canoeing reflected in his approach to triathlon. “He knows what it takes to actually get somewhere with his training,” he says.

That determination is also something Matej brings to those around him. His motivation and positive energy can lift the atmosphere during training. “He knows how to hype himself up,” says Coach Dhill. “Whenever he does it, everybody at the session also ends up in a positive mood.”

The moment it all came together

 

After almost ten months of preparation, Matej finally took on the race in Krakow, Poland.

As Matej approached the finish line, the enormity of what he had achieved suddenly caught up with him.

“I remember looking at the finish line for the first time. I don’t think I’ve ever had such goosebumps,” he says. “The whole ten months of preparation flashed in front of my eyes.”

He crossed the finish line in 5:47:29, taking a moment to appreciate what he had accomplished before the fatigue finally caught up with him.

However, the race itself is only part of what made the experience worthwhile. The bigger achievement was everything that happened in the ten months leading up to it: learning to manage competing priorities, adapting when things went wrong, staying consistent when motivation disappeared and finding ways to connect his interests across sport and academics.

He also credits his family, friends and school for helping him reach the finish line.

“Without their support, I could only dream of having such an opportunity,” he says. “It made me realise how important it is to value your family, as they were the ones who were always telling me that the sky is the limit.”

On to the next challenge

 

Matej’s journey is a reminder that achievement does not always follow a straight line. Sometimes it means changing direction, trying something completely new and learning how to adapt when things do not go according to plan.

His advice to other learners is simple:

“Do not be afraid to try new things. Make sure you find something that makes you forget IB for a while, so your mind can refresh a bit. Do not care what others think. At the end of the day, you matter.”

After seven years of sprint canoeing, an IB Mathematics IA inspired by endurance sport, mathematics competitions and now an IRONMAN 70.3, Matej is certainly not short of challenges to pursue.

And, true to form, he is already looking towards the next race.
