Stop guessing your training zones. At Tempo Endurance Coaching, we use lab-level lactate testing to create a digital twin of your physiology, replacing generic heart rate data with precision. We measure: LT1 (Aerobic Threshold) for base building; LT2/MLSS (Anaerobic Threshold) for peak power; VLamax for glycolytic capacity; and FatMax/CarbMax for exact fueling. Get a data-driven plan that maximizes adaptation and minimizes strain.

The Tempo Advantage: Powered by INSCYD

We don't just give you a number; we give you a strategy. Using the INSCYD metabolic profiling system, we validate your Anaerobic Work Capacity to set training zones that are truly individualized. The result is a higher rate of adaptation with less total strain on your system.

Individualized Zones

No more "one-size-fits-all" percentages; zones based on your specific metabolism.

Fueling Strategy

Know exactly how much you need to eat to avoid the "bonk" during races.

Historical Tracking

Monitor how your lactate curve shifts to the right as you get faster.

Performance Benchmarking

Compare your metabolic fingerprint against your specific athletic category.

Test Logistics & Pricing

Testing is performed in-studio at our Kentfield location using medical-grade lactate analyzers.

• Ala Carte Testing: $275.00 per session.

• Performance Bundle: 4 tests for the price of 3 ($600.00 upfront).
