Cycling lactate test analysis: calculate LT1, LT2 and power zones

For cycling, the analysis is especially direct: watts are stable to measure and translate cleanly into training ranges.

Cycling protocol

A good cycling protocol uses constant stages and moderate power jumps.

  • 3-5 minutes per stage
  • 20-30 watt increases
  • Measure lactate at the end of each stage
  • Keep cadence consistent

Power zones

LT1 and LT2 are translated into watt ranges and can be compared with FTP.

  • Zone 2 ends closer to LT1 than to generic FTP percentages
  • LT2 helps with sweet spot and threshold intervals
  • VLamax context helps with pacing

Analyze your own lactate values

Enter pace or power and your measured lactate values. LactateThreshold calculates lactate curve, LT1, LT2, VLamax and training zones.

Why you can trust the analysis

LactateThreshold does not turn measurements into false precision. The app shows the curve, method comparison, plausible thresholds and the limits of your test protocol transparently.

Frequently asked questions

Is LT2 the same as FTP?

Not exactly. LT2 is derived from lactate values, while FTP is a performance estimate.

Do I need a smart trainer?

An ergometer or power meter with stable output is enough. The key is constant load.
