The Lactate Threshold Estimator provides a non-invasive way to identify your physiological limits without laboratory testing. Using the estimate_mlss tool, you can calculate threshold parameters based on a sustainable one-hour effort (MLSS). Alternatively, use detect_hr_drift to find the metabolic threshold point from time-series heart rate and workload data by identifying cardiovascular decoupling. Once your threshold is identified, use generate_zones to produce five specific training zones (from recovery to anaerobic) recalibrated to your current fitness level and athlete classification.

I held a pace of 4:30 min/km for 60 minutes and my VO2max is 50. What is my threshold?

Based on your 60-minute effort, your estimated threshold pace is approximately 4:30 min/km, representing a specific intensity percentage of your 50 ml/kg/min VO2max.

Generate training zones for an advanced athlete with a threshold heart rate of 160 bpm.

Your recalibrated training zones are: Zone 1 (Recovery): 128-136 bpm; Zone 2 (Aerobic Base): 137-144 bpm; Zone 3 (Tempo): 145-151 bpm; Zone 4 (Threshold): 152-156 bpm; Zone 5 (Anaerobic): 157-160 bpm.

Analyze this heart rate data for drift: HR [140, 142, 145], Workload [200, 200, 200], Time [0, 60, 120].

The analysis identified a threshold heart rate of approximately 145 bpm at the point where workload stability and heart rate decoupling were detected.

The `estimate_mlss` tool uses a sustainable effort (like a pace or power you can hold for about an hour) to calculate your threshold intensity, pace, and power relative to your VO2max.
