Metabolic & Field Testing

INSCYD, VO2 Max & Threshold Testing

Why Testing Matters

Training is most effective when it’s built on accurate, individualized data—not guesswork. Metabolic and field testing gives you a clear understanding of how your body produces energy, how you respond to different training intensities, and what specific systems you should target to make the fastest progress. Whether you’re preparing for a race, rebuilding fitness, or trying to break through a plateau, testing provides the roadmap.
​
With the right data in hand, you can train smarter, fuel properly, and see measurable improvements—on any terrain, in any discipline.

INSCYD Metabolic Testing

A Complete Internal View of Your Physiology

INSCYD is the gold standard in metabolic profiling, used by WorldTour teams, elite coaches, and performance labs around the world. Instead of relying solely on FTP—which only tells part of the story—INSCYD reveals the full picture of how your energy systems work and how to improve them.

What INSCYD Measures

✓ VO₂max — Your aerobic engine
✓ VLaMax — Glycolytic capacity (the key to sprinting ability and endurance efficiency)
✓ Anaerobic Threshold (FTP) — Metabolic threshold, but with deeper context
✓ FATmax — Peak fat oxidation rate
✓ Carbohydrate & Fat Combustion — Fueling demands at every intensity
✓ Aerobic vs. Glycolytic Contribution — What’s powering your efforts
✓ Economy & Efficiency Metrics
✓ Recovery & Fatigue Insights

Actionable Training Insights

Your results translate directly into decisions that improve performance:
✓ Your fastest path to reaching key race or event goals
✓ Precise interval prescriptions based on lactate production and clearance
✓ Recovery intensities based on your actual physiology

Threshold Field Test

90-Minute Real-World Power Test (Indoor or Outdoor)

To train effectively, you need to know your correct intensity levels—not generic percentages or outdated estimates. A Threshold Field Test identifies your personal heart rate and/or power thresholds, giving you precise training zones that make every workout more productive.

Whether you train indoors or outdoors, with heart rate or power, this test provides the foundation you need to progress efficiently and safely.

Why Threshold Testing Matters

Even the best training plan won’t deliver optimal results unless it’s executed at the right intensity. Threshold testing gives you:
- Accurate power and heart rate zones
- A clear benchmark of current fitness
- Specific intensities for intervals, recovery, endurance work, and race prep
- A consistent method for tracking fitness throughout the year
- Event-specific strengths & weaknesses
​- Insight into which physiological areas need attention

Who It’s For

- Athletes building toward structured training
- Riders wanting validated power or HR zones
- Cyclists aiming for time trials, fondos, or race prep
- Anyone starting a coaching program with Brian

What You Receive

Every test includes:
- Full data analysis
- Personalized heart rate zones
- Personalized power zones (if applicable)
- Electronic delivery of all test results
- A post-test debrief to discuss findings and next steps

How the Test Works

The Threshold Field Test takes approximately 90 minutes and can be performed:
- Outdoors on a suitable stretch of road
- Indoors on a trainer using your preferred setup
Brian will guide you through:
1 - A structured warm-up
2 - The test protocol
3 - Cooldown and data capture
4 - Post-test data submission
Once your data is analyzed, you’ll receive personalized training zones and actionable guidance.
