Johannes Kjellgren

"Nemanja has been my triathlon coach since October 2014. He coached me to my first Ironman finish in Nice 2015 and has continued to challenge me for new goals in 2016, Challenge Venice. With a busy work and private schedule, you really have to make "smart trainings" and I have to say that Nemanja is great in creating training plans that still kept sufficient time for my private and work obligations. Nemanja is also very knowledgeable about nutrition and all aspects of being an athlete whether you are an amateur or professional."

Jelena Jankovic Laskovic

"Nemanja has been my long distance triathlon coach since march 2015. He is focused, very knowledgeable, reliable and dedicated to his work. His training plan successfully led me to the finish line of two Half Ironman triathlons along with my busy everyday schedule. Nemanja focuses on each client and ready to perfectly modify very busy training plan if necessary."

"Nemanja is my coach and he has been coaching me for 3 years. With his expertise and professionalism he made all my triathlon goals possible, even I have full time job. Just after 2 years of triathlon training under Nemanja's supervision I have finished my first Ironman 70.3 with really good time (4:49:00). He like to hear how you feel in certain part of preparation and know to adapt training and point out your mistakes. I am happy i got in triathlon with Nemanja as my coach, it would be much harder without him."
