Matěj König is one of the most prominent Czech sports content creators and influencers. Since starting out in 2021, filming his first videos with a tripod in his garden, he has built a community of hundreds of thousands of followers across social media. His content combines sport, entertainment, and motivation — from demanding challenges such as an Ironman and marathon to collaborations with professional athletes and behind-the-scenes glimpses into his life as a creator.

In 2026, Matěj expanded his creative journey by publishing his first book, Takhle zní vítězství: Sportuj s Matějem. Aimed primarily at young readers, the book tells his personal story — from childhood and his passion for sport through the beginnings of his social media career, successes and setbacks, all the way to completing an Ironman. QR codes with exclusive videos connect the book with his online world and bring readers even closer to his journey.

At the heart of Matěj’s story are sport, perseverance, pushing personal limits, and the courage to start. Through both his online content and his book, he encourages young people to believe in themselves, take on new challenges, and pursue their goals.
