BUILD A HYROX ENGINE THAT DOESN'T BLOW UP.
Stop guessing your pacing. We measure exactly how your body burns fuel so you can run faster, push harder, and finish strong.
Why do I feel great for the first 20 minutes, then crash?
It’s not because you aren’t fit. It’s because you are running blind. Most Hyrox athletes guess their pacing. They go out too hard on the first run, burn through their carbohydrate stores on the sled push, and have nothing left for the wall balls.
The Hyrox Metabolic Project changes that. We don't just give you a training plan. We take you into the "Lab" (In-Person or Remote) to pop the hood on your engine. We measure your:
Fuel Gauge: Exactly how many grams of carbs you burn at race pace (so you know how to fuel).
Fatigue Point: The exact heart rate where your body starts to red line.
Race Pace: The optimal pace for training and racing
It’s not about just pushing through; it’s about understanding how to improve so every session moves you towards your goals
From Data to Performance
THE SCIENCE OF YOUR ENGINE Most fitness tests (like an FTP ramp test) only measure your output. They tell you how fast you are, but not why. We go deeper. By measuring your Lactate Production Rate (VLamax), we look inside the engine to see exactly how your body creates energy.
STEP 1: THE METABOLIC AUDIT
The Protocol: We take you through a specific graded protocol (running or cycling) designed to stress your aerobic and anaerobic systems independently.
The Measurement: We don't just watch your heart rate. We measure Blood Lactate accumulation.
Why this is superior: Lactate is the direct byproduct of burning carbohydrates. By measuring it, we can calculate with clinical precision exactly how much sugar vs. fat you are burning at every single intensity zone. No other test gives you this level of fuel clarity.
STEP 2: THE "VLamax" REVEAL
The Secret Metric: We identify your VLamax (Maximal Lactate Building Rate).
Why it matters for Hyrox:
High VLamax: You have a "Ferrari" engine. You are explosive on the Sleds, but you burn fuel too fast and "gas out" on the runs.
Low VLamax: You have a "Diesel" engine. You can run forever, but you lack the punch to move heavy weights quickly.
The Fix: Standard FTP testing ignores this completely. We measure it so we can train it.
STEP 3: THE PERFORMANCE BLUEPRINT
The Pacing Strategy: Because we know your exact "Combustion Rate" (grams of carbs/hour), we give you a precise Race Day Pacing Plan. You will know exactly how hard you can push the Sled Push without tipping over into "metabolic failure."
The Training Block: We build your 4-week or 12-week plan specifically to fix your VLamax. If it's too high, we lower it. If it's too low, we build it.

HOST A HYROX TESTING DAY
We bring the full metabolic testing setup to your Gym, CrossFit Box, Running Track or Training Centre.
Training is better in a team. Testing should be too. If you have a squad of athletes training for Hyrox, we can set up a Mobile Lab at your facility to test everyone in a single session.
THE GROUP ADVANTAGE
Volume Pricing: Significant discounts for groups of 6 or more athletes.
Coach Integration: We explain the differences between each athlete and how training can be tweaked to perform better with more individualised training
The "Combine" Atmosphere: Turn testing into a team event. Support each other through the protocol and get your numbers together.
WHAT WE NEED FROM YOU
Access to 1-2 reliable Treadmills
A small space for our analysis station.
A team ready to find their limits.
GYM OWNERS & COACHES Want to offer clinical-grade testing as a premium service to your members? We offer Partner Rates and Revenue Share models for gyms that host regular testing days.
FAQs
Frequently Asked questions
-
Both methods lead to the same physiological outcomes and training guidance.
In-person testing uses blood lactate sampling and controlled intensity steps.
Remote PPD testing uses structured maximal efforts completed in your own environment and analysed using INSCYD modelling.
The difference is how the data is collected — not what we can determine from it.
-
If you’re local and can attend in person, lactate testing offers a highly controlled environment.
If you’re remote or prefer flexibility, PPD testing provides excellent accuracy when the protocol is followed.If you’re unsure, book the main testing option and we’ll confirm the best route.
-
For remote PPD testing you’ll need:
A GPS watch (Garmin, Coros, Polar, etc.)
The ability to record and upload .FIT or .TCX files
In-person testing equipment is fully provided.
-
The full PPD protocol is relatively short and can be completed:
In a single session
Or split across 1–3 days if needed
In-person lactate testing typically takes 60–90 minutes.
-
You’ll receive:
A full physiological performance profile
Accurate thresholds and training intensities
Identification of your key performance limiter
A 1-to-1 results consultation
Clear guidance on how to train differently
You are not left alone with the data.
-
Single-metric tests estimate performance from one effort.
PPD and metabolic testing:
Model your entire performance curve
Separate aerobic limits from lactate limitations
Explain why you fatigue, not just how fast you are
This allows far more precise training decisions.
-
All data is quality-checked using INSCYD’s validation system.
If accuracy is insufficient, we will ask you to repeat part or all of the test to ensure reliable results.
We prioritise correct answers over convenience. -
No. The protocol is scalable and suitable for:
Intermediate to advanced athletes
HYROX, triathlon, and endurance competitors
If you have medical concerns, contact us before booking.
-
Yes, this is particularly valuable for self-coached athletes.
It provides objective clarity on:
What to prioritise
Which sessions matter most
How hard you should actually train.
-
Absolutely. Many athletes share their results directly with their coach to improve training accuracy and communication.
