Why have you chosen your sport and how long you have been doing it?

As a true Belgian/Flandrien, I got into triathlon through cycling. I started my triathlon journey in 2018. In 2020 it got a lot more serious when I started working with a coach. For me, the variation in training is a plus, but I also like the importance of nutrition – the fourth discipline – in long distance racing. Because of the importance of nutrition, I’m so glad I get to work with INFINIT in a very close way.

What motivates you to compete? What is your why?

So many things. The progression I can feel myself making, the triathlon community – my teammates but also the wider community for example at races or online -, the attention for detail – aerodynamics, nutrition, recovery… - and last but not least the places you get to race through triathlon. Whether it’s a local race on roads you train on so often, or places far from home with people from all over the world.



When I studied Journalism, one of the big lessons I kept getting told in college was KISS (“Keep it simple, stupid”). Now, several years later, I try to apply that to triathlon. Why complicate nutrition when it can be simple as well. With INFINIT, I just know I need to drink X amount of bottles in X amount of time to get X amount of carbs and X amount of hydration. That, and the fact that the taste of the products is just sublime!

Any recommendations or sport hacks that you would like to pass to the athletes in your sport?

Masters the details: whether it is nutrition (Staying on top of carb intake or monitoring your salt intake), race dynamics (learning to ride together with people, even with a 12 of 20 meter no draft zone) or transitions.

Which INFINIT product you like the most and why?

This is a tough question. I’ve got several products as mentioned before, but if I had to choose one… :GOFAR fruit punch. Hot or cold conditions, with :GOFAR I know I’m getting in plenty of carbs, so that’s one less thing to worry about while training or racing.

Your motto or the best motivation line for the start of the week that gets you going?

If it was easy, everybody would be doing it.
