Silke Werkhoven

Hi, I’m Silke, also known as @fitbysilke. I’m a passionate runner on a mission to break the 3-hour mark in the marathon. When I’m not logging miles on the road, you’ll find me on the bike, I even founded a cycling group in Friesland to bring people together through movement. Through every high and low, I share my journey authentically to inspire others to move with purpose, grow through challenges, and push beyond their limits.

Jente Hauttekeete

Athletics (All-Around)

I am an athlete who is not easily satisfied with a performance. I always want to do better than the previous race and keep improving my personal records. I like to learn quickly. Sometimes I try to imitate or learn a technique by watching other athletes. I am very motivated during training and I don't give up easily, but sometimes I dare to let my head hang down when things don't go as I had hoped. I am always open to humour and jokes on and off the slopes.

Nanoi Van Wettere

Cycling

I am Nanoi Van Wettere, 18 years old, and I grew up in the world of cycling. Although I briefly explored the world of dance as a young girl, I quickly left it behind when I asked for a racing bike for my first communion. Since then, I've been passionate about cycling for 10 years. Through this sport, I've had the chance to experience many unique moments and travel the world. In addition to cycling, I am also studying nutrition and dietetics.
