Stop guessing.
Train from your actual physiology.
Lab-grade metabolic and strength testing that shows you exactly how your body makes energy, burns fuel and holds pace — then turns it into a plan you can run.
Real numbers from athletes we've profiled
A full MOT for your endurance engine
The 360° Metabolic Profile brings together a precision lactate test and INSCYD metabolic modelling, an RMR resting-metabolism test, a gait analysis of your running mechanics and a VALD ForceDecks strength screen. Together they reveal the hidden numbers behind your performance — the ones a GPS watch can never show you.
Instead of training on generic zones and hoping, you get pace and heart-rate zones, a fuelling strategy and a strength plan built around your physiology. It's the same testing approach used with elite endurance athletes, made accessible to you.
- Know precisely where your threshold, fat-burning and fuelling limits sit
- Train every session in the right zone, for the right reason
- Fuel races so you never hit the wall again
- Fix the strength imbalances quietly costing you speed and durability
Your metabolic fingerprint
Illustrative profile — every athlete gets their own, plotted against a trained-athlete band.
The numbers that decide your races
Each one is measured, explained in plain English, and turned into something you can act on.
VO₂max
The maximum oxygen your body can use to make energy. It sets the ceiling for every pace you can hold — the bigger the engine, the higher your potential.
Athletes tested up to 76 ml/min/kgVLamax
How fast you produce anaerobic energy. Low means an efficient endurance "diesel" that sips fuel; high suits sprinting but burns carbs fast. The single biggest lever on an endurance profile.
As low as 0.11 mmol/l/s measuredAnaerobic Threshold (MLSS)
The fastest pace you can hold before lactate runs away from you — and what percentage of your VO₂max that represents. The higher the %, the more of your engine you actually get to use.
Up to 99% of VO₂max in athletes testedFatMax
The intensity where you burn the most fat, sparing precious carbohydrate. A big fat engine is what keeps you strong in the final miles instead of fading.
Peak fat burning up to ~86 g/hCarbMax
The pace above which carbohydrate demand climbs steeply. It tells you exactly when a fuelling plan stops being optional and starts deciding your result.
Pinpointed to your pacesGlycogen store
How much carbohydrate you can store — and, at your race-pace burn rate, exactly how long it will last before you need to top up.
~550–600 g stores mapped to race timeLactate dynamics
How you produce and clear lactate across a range of paces — the measured foundation the entire metabolic model is built on, so your profile reflects reality, not estimates.
3-stage measured lactate curvePersonalised zones
Precise pace (and heart-rate) zones from recovery to VO₂max — so every easy run stays easy and every hard session hits the system it's meant to.
7 zones, pace-led + HRStrength & asymmetry (VALD)
Force-plate testing of single-leg power, jump height, stiffness and reactive strength — exposing left/right imbalances that quietly cost you economy and raise injury risk.
L/R imbalances flagged over 10%Gait analysis
A detailed look at how you actually move — cadence, ground-contact time, stride, foot-strike and left-to-right symmetry. Small mechanical tweaks translate straight into free speed and fewer injuries.
Cadence, contact time & symmetryRMR — resting metabolic rate
A simple breathing test that measures how many calories you burn at rest, and whether you're running on fat or carbs. The foundation for getting body composition and daily fuelling right.
Your true daily calorie & fuel baselineFrom test to plan in four steps
Around 60–90 minutes on the day. A detailed report and coaching plan shortly after.
Metabolic testing
An RMR resting-metabolism test, then a structured, staged lactate effort with a small sample at each stage — mapping how you make and burn energy from rest to race pace.
Movement & strength
A gait analysis of your running mechanics plus a few jumps on VALD ForceDecks — capturing form, single-leg power, stiffness and left-to-right asymmetry.
INSCYD analysis
Your measured numbers are modelled into a complete metabolic profile — VO₂max, VLamax, thresholds, fat & carb burning and fuelling.

Good to know
Not at all. The profile is calibrated entirely to you — it's just as valuable for a motivated club runner as for a national-level athlete. It simply meets you where you are and shows you the fastest way forward.
You'll do a structured, progressive test effort with a small finger/earlobe blood-lactate sample taken at each stage, plus a short series of jumps on the VALD force plates. Expect to be with us around 60–90 minutes.
It's built around running, but the underlying metabolic model applies to cycling and triathlon too. If you're an endurance athlete, the numbers are relevant to you — just ask us about sport-specific testing.
Every 10–12 weeks is ideal. That lets you confirm your training is working — that VO₂max and threshold are climbing while your endurance efficiency holds — and refresh your zones as you improve.
