🧠 HYROX Performance Test
Understand your race engine. Master your pace.
What We Measure
This test isn't about who's the fittest — it's about how your body handles the race.
During HYROX, you don't fail because you're weak. You fail because your body builds up more fatigue than it can clear between stations.
Our performance test measures exactly that.
We test:
- How much lactate you produce during each station
- How quickly you clear it on the following run
- Which stations hit you the hardest
- How close you are to your ideal race intensity
The pattern tells us:
- Whether your pace is sustainable
- How well your body recovers between stations
- Which movements cause the biggest metabolic spikes
How It Works
You'll run 1 km at your ideal race pace (from your Race Pace Test). Then you'll complete a HYROX station at a strong, race-style effort. We take a small blood sample after the station — and again during the next run — to track how your body responds.
This repeats across several stations to build your individual performance map.
The pattern tells us:
- Whether your pace is sustainable
- How well your body recovers between stations
- Which movements cause the biggest metabolic spikes
What Good Looks Like
A great result doesn't mean "low lactate." It means your lactate rises and falls in waves — up after a station, down on the runs — showing that your system can handle the workload.
⚠️ Warning Signs:
- • If your lactate keeps climbing, you're going too hard too soon
- • If one station sends it through the roof, that's your limiter
✅ We use this data to:
- • How fast to run between stations
- • Where to back off slightly
- • What to train to improve recovery and endurance
Why It Matters
Every HYROX athlete has a different engine. Some are powerful but burn out. Others can go forever but lack punch.
This test shows us exactly how your engine works — so we can help you race smarter, not harder.
What You Get
📊 Analysis Includes:
- Personal lactate graph showing production and recovery
- Breakdown of your strongest and weakest stations
- Race-pace recommendations (when to push, when to hold)
- A simple plan to improve your endurance and efficiency
In Simple Terms
"We find your red line, show you how to stay just below it, and teach your body to clear lactate faster — so you can run stronger, longer, and finish harder."
