This test gives you a clearer picture of what is happening inside your body when you train. Instead of guessing your zones, fuelling needs, or race pacing, you get data that helps you make better training decisions.
VO₂max & VLamax insight.
+
Understand your aerobic capacity and glycolytic contribution.
Fat & carbohydrate utilization.
+
See how your body uses fuel across different intensities.
Training recommendations.
+
Turn the results into practical actions for your next training block.
What's included
Testing that turns data into decisions.
Metabolic Report
A clear breakdown of your physiological profile, including the key metabolic markers that influence your cycling performance.
Energy Utilization
Understand where your body relies more on fat or carbohydrates and how that changes with intensity.
Training Zones
Personalized zones that reflect how your body actually responds, not generic formulas or assumptions.
INCLUDED
Performance Strategy
Specific guidance on how to use your results to improve training structure, pacing, and progression.
INCLUDED
Coach Interpretation
Your results are explained in simple language, with practical next steps and priorities.
Remote Setup
Complete the process without needing to be physically present, with guidance for accurate data collection.
WHY IT MATTERS
Train from physiology. Not percentages.
INSCYD PPD Test, defines training targets from your individual physiology — not from predefined %FTP ranges that may not reflect your metabolic response.
More precise training decisions
01
Zones based on your physiological benchmarks.
Training intensities are based on your VO₂max, VLamax, and metabolic markers — rather than predefined FTP percentages.
02
Better control of the intended training stimulus.
Each session can target the correct physiological response, whether the goal is aerobic development, selecting the most effective recovery intensity for lactate clearance between HIIT efforts, or reducing glycolytic contribution.
03
Understand the energy and carbohydrate demand.
See how much energy comes from fat and carbohydrates at different intensities, helping you pace more accurately and match your fuelling to the demands of each training session or race.
Who is this for?
For cyclists who want decisions based on physiology.
From beginners to pros—accurate physiological insight for every level of performance.
The rider ready to move beyond predefined FTP zones.
You want training intensities based on your individual aerobic and glycolytic profile rather than fixed percentages.
+
The rider whose progress has plateaued.
You train consistently but need to identify whether aerobic capacity, glycolytic demand, or fuel utilisation is limiting further progress.
+
The competitor preparing for a specific event.
You want more precise pacing and training targets, along with carbohydrate intake recommendations based on your carbohydrate utilisation at different exercise intensities.
+
The elite athlete who wants to measure progress objectively.
You want a physiological baseline that can be repeated later to evaluate how your training has changed your metabolic profile.

What gets measured can be trained. What gets understood can be improved.
