Burn more fat, save carbs, and keep pushing when others fade.


Most athletes don’t really know how their body fuels itself. They guess, follow generic advice, or hope gels and sports drinks will do the job. It works for a while. Then it doesn’t.

A metabolic test shows how your body burns fat and carbs at different intensities. With that clarity, you can fuel smarter, train better, and go further with less.

« Before you test

You are not sure how well your body burns fat. Energy can feel unstable. Hunger shows up often. Long sessions may end with you hitting the wall or struggling to fuel consistently.

After you test »

You know where your energy comes from at different intensities and how efficiently you burn fat. More importantly, you know how to improve it.

That clarity lets you lose fat more easily, fuel races with confidence, and go longer and faster without relying so heavily on gels, bars, or sports drinks.

How it works

You’ll do a ramp test on a treadmill or bike while wearing a mask that measures your breath — oxygen in, carbon dioxide out. From that, we see what fuels you’re burning at each effort.

Two key points come out of this:

  • Fatmax: where fat burning peaks.
  • Crossover: where you switch from mostly fat to mostly carbs.

These show your current metabolic state and guide clear recommendations for training, diet, and lifestyle.

See the improvement

With the right training and nutrition, fat burning improves. You’ll see it in the data. Higher Fatmax. A later crossover point.

You’ll feel it day to day too. More stable energy. Less unwanted body fat. Stronger endurance that lasts.

FAQ

What’s the difference between a metabolic test and a lactate test?

A lactate test focuses on your thresholds and training zones. A metabolic test focuses on what fuels you’re burning (fat vs carbs) at different intensities. Both are valuable, and together they give the clearest picture of your fitness.

What’s the difference between a metabolic test and a VO₂max test?

A VO₂max test measures the maximum amount of oxygen your body can use during intense exercise — essentially your aerobic engine size. A metabolic test, on the other hand, looks at how your body uses different fuels (fat vs carbohydrate) across a range of intensities.
Think of VO₂max as the capacity of your engine and metabolic testing as how efficiently that engine runs on different fuels.

Do I need to prepare for the test?

Yes. Arrive well-rested, hydrated, and avoid heavy training 24 hours before. Please don’t eat or drink (except water) for at least 4 hours before your appointment.

Who is this test for?

It’s useful for anyone — from athletes who want to optimise race fuelling, to people looking to lose body fat, stabilise energy, or improve metabolic health.

Will I need to do both the running and cycling test?

No. Choose the test that matches your main sport.

If you train and race in both, you can do both for a complete picture. If you’re choosing one, test your weakest discipline, or the bike. It’s the biggest part of a triathlon.

How often should I repeat the test?

We recommend every 3–6 months to track progress and adjust your training and nutrition plan.

Is it uncomfortable wearing the mask?

It can feel unusual at first, but most people adapt within a few minutes. Our consultants guide you through and make sure you’re comfortable.
