Overview
Lactate Threshold Testing is one of the most accurate ways to understand how your body performs under physical stress. By analysing blood lactate levels at progressively increasing intensities, we identify your true LT1 and LT2 thresholds — the foundations of precise, personalised training zones.
This test gives runners, cyclists and endurance athletes deep insight into aerobic capacity, sustainable pace, fat vs. carbohydrate utilisation, and how to structure training for maximum progression. If you’ve ever felt unsure whether your “easy” is easy enough — or whether you’re working in the right zones for race day — lactate testing gives you absolute clarity.
Using hospital-grade equipment and protocols validated in elite sport science, our team delivers detailed insights you can confidently train to.
Who It’s For
-
Runners preparing for races from 5K to ultra
-
Cyclists and triathletes seeking precise and personalised training zones
-
Anyone wanting to train smarter, not harder
-
Athletes plateauing despite consistent training
-
Individuals looking for metabolic insight to reduce fatigue and improve pacing
-
People who want accurate LT1/LT2 markers (not estimated, not guessed)
Why It Works
Your lactate thresholds determine:
-
How fast you can sustainably run
-
How long you can hold race pace
-
The exact zones that build aerobic efficiency
-
Where fatigue begins and why
-
How to avoid overtraining and burnout
Most athletes train “blindly” using heart rate formulas, wearables or online calculators that can be wildly inaccurate. Lactate testing gives you your numbers, not estimates.
