To begin answering that, HYROX has established a global Science Advisory Council and published its first Sports Science of HYROX Report, a publication built around the peer-reviewed research most relevant to the sport today. Together, they signal a shift in emphasis. Growth alone is no longer enough. Understanding is the vital next step.
“At this stage of HYROX’s development, science is not optional,” says Ralf Iwan, Chair of the Science Advisory Council and Head of the HYROX365 Academy. “As the sport continues to evolve into a globally recognised competitive format, that growth has to be underpinned by rigorous, evidence-based research.”
At the centre of the council’s work, is the idea that HYROX is now large enough to be studied with academic rigour. Fixed distances, repeatable workloads, and consistent race design create conditions more commonly associated with endurance sports, such as marathon running or Olympic lifting. Meaningful data can accumulate quickly and performance can be studied over long time periods.
Dr. Adam Storey of the Sports Performance Research Institute of New Zealand, a member of the council, sees that standardisation as fundamental. “HYROX’s consistency gives the sport scientific credibility,” he says. “It means we can measure, compare, and replicate results anywhere in the world. That’s what allows insights to deepen over time. It’s the same principle that turned marathon running into a global benchmark. Through the Science Advisory Council, competition becomes data.”
The Science of HYROX Report reflects that mindset. Rather than offering definitive conclusions, it maps the current evidence landscape. It outlines what is already understood about training load, physiological stress, and performance characteristics, while clearly identifying where gaps remain. The report is less a verdict than a starting point, designed to guide what should be studied next as participation continues to grow.
For Iwan, that openness is deliberate. “Inviting scrutiny from the scientific community is essential,” he says. “This council brings together experts from different disciplines who are actively engaged in research relevant to HYROX. The goal is to deepen understanding, challenge assumptions, and build a credible scientific foundation for the sport.”
Crucially, the work is intended to transfer beyond the realms of academic journals. Findings from the council feed directly into the HYROX365 Academy, shaping how coaches are educated and how athletes prepare. With more than 75,000 coaches globally now on HYROX performance pathways, even incremental improvements in understanding can have wide-reaching benefits to training culture and athlete wellbeing.

“There is real value in closing the loop between research and practice,” says Storey. “When coaches understand why certain demands exist, and athletes understand how their bodies are responding, performance improves and risk is reduced.”
There is also a longer horizon in view. As HYROX continues to position itself alongside established competitive sports, scientific credibility becomes part of its infrastructure rather than an added layer. Publishing research, supporting independent study, and creating an annual cycle of review and refinement signals a sport confident enough to be stand up and by measured.
The Science Advisory Council will expand over time to include a broader international research network, alongside structured input from athletes and coaches. Annual reports, dedicated symposia, and targeted research projects will form a continuous evidence cycle.
The first of those symposia will take place at the HYROX Coaches Summit in March 2026. By then, the ambition is clear. Not simply to describe HYROX as it is today but to help shape what it becomes next.
