Both critical speed and critical power are well-established concepts in sports science. They represent the threshold separating sustainable metabolic work from unsustainable effort. Do you want to know your own hyrox pace? Have a look at our self-made calculators. For running: https://criticalspeed.streamlit.app/ For ergometers work: https://critical-power.streamlit.app/ Given the additional fatigue imposed by the competition demands, the Hyrox running and ergometer pace can be set between 85% and 95% of critical speed, corresponding to Zone 5 intensity in the app. More information can be found on our blog: https://www.motusathletic.com/blog/critical-speed-and-critical-power-concepts-for-determining-hyrox-performance
