I am Sofia Costoulas, I was born in Genk and I am 16 years old. I started playing tennis when I was 4 years old and I still love it. I study human sciences and besides tennis I like to be creative. My biggest hobby is Pokémon, both Pokémon games and collecting Pokémon cards. I am a great animal lover, so if I didn't travel so much it would be Pairi Daiza at home ;-) My biggest dream is to take part in the Olympic Games and win a medal for Belgium.

My conviction for choosing Etixx as sports nutrition partner
Because Etixx has qualitative good products, they have a lot of choice and variety and they have the informed sport quality label so I don't have to worry in case of a doping control.

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.Lee mas
I am Marith Vanhove and I’m 17. I am in my last year at the Topsportschool in Ghent where I am studying modern languages and top sport. I have been racing in competitions at the highest level for 10 years now and later I would really like to build a possible professional career. In addition, I am also very sociable and easy to get on with and I like helping people when they need it. The Etixx products give me the chance to achieve my goals and give the best of myself in training. It also really nice to be able to try out the latest products and share my experiences with my followers. I have had experience using Etixx products for a number of years and I am also very satisfied with them! Becoming an ambassador of my favourite sports nutrition brand is also great motivation to work toward my next big goals!Lee mas
