About STYREKX
STYREKX was born from years of experience in pushing the limits of sport and creating unforgettable event experiences. Discover the perfect balance between strength and endurance.
From outdoors to indoors
Who are we?
STYREKX was born from Strong Viking and years of experience creating world-class sporting events. No mud and no outdoor obstacles, but the same raw intensity transformed into a powerful indoor fitness race.
What STYREKX stands for
Mission & Vision
STYREKX brings strength, endurance and competition together in one unique indoor challenge. We create an environment where athletes can test themselves, push their limits and grow stronger together. A podium finish is great, but becoming the fittest version of yourself is even better.
Our vision is to set a new standard for fitness racing. Professionally organised, accessible to athletes of all levels, and built around energy, atmosphere and performance.
Where it all began
The Story Behind STYREKX
STYREKX was founded in 2025, but its story really began back in 1982, in the gym of founder Jan Reijs’ father. That’s where his passion for fitness and sport first took shape.
After years of experience with Strong Viking, the idea for a new concept was born: a fitness race where strength and endurance come together in one unique challenge.
What does STYREKX mean?
The Story Behind the Name
The name STYREKX is inspired by Old Norse. STYRKR represents strength, while ÞREK symbolises endurance and inner resilience. The X stands for the unknown, the limits you push beyond, and the maximum you can achieve.
Together, STYREKX represents physical strength, mental resilience, and the determination to keep going when the challenge is at its toughest.
The Power of X
The power and balance of the ultimate number
The number 10 represents perfection. The highest level of performance. Ten times you push. Ten times you give everything you’ve got. Ten opportunities to rise above your own limits.
At STYREKX, you chase that perfect ten by testing your endurance ten times and giving every last ounce of strength at all ten workout stations. Are you ready to race?
STYREKX is a (hybrid) fitness race with a fixed structure: 10x 800-meter runs alternated with 10 functional workouts.
STYREKX is suitable for athletes of all levels. There are separate categories for solo, duos, and teams.
