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.

After a (youth) career in athletics, I switched to the Belgian bobsleigh team. After a few years, I retrained from brakewoman to pilot, while also completing my Masters in physiotherapy. In 2015, I was employed part-time by Sport Flanders as pilot and I am now about to start my 10th bobsleigh season. Qualifying for the Olympic Winter Games in 2018 was an amazing feeling and made me dream of doing more in 2022, in Beijing. I now practise my sport full time, while also being a proud Godmother to my nephew, the apple of my eye. I am very proud to be part of the Etixx ambassadors team, a super-talented and motivated group of athletes and sports enthusiasts. Being supported by such a professional company with good-quality, clean products gives me an extra push to achieve my dream of a top result in Beijing 2022!Lee mas
I am a 400 m runner and Belgian Cheetah (4x400m) with a few years of bad luck and injuries behind me. The Etixx products help during everyday recoveries and provide the necessary supplements for a top athlete, but also helped during my rehabilitation. The Etixx range is very broad and comprises everything, for every possible sports discipline. As a top athlete, you are also checked regularly for doping, so it’s great that. with Etixx, I don't have any concerns about that with their ‘Informed Sport’ quality label.Lee mas
I am primarily someone who doesn't give up easily and who sees everything positively. In addition to running for myself recreationally (60-100 km/week), I am also Charlotte Van Hese’s trainer. The aim is to make her a real top athlete without her losing the pleasure of running. The Etixx products are a fantastic asset for my (now much less) injury-prone body. I am very proud to be a part of this top team!Lee mas
