How to Read Strava Data Correctly: Making Data a Tool for Your Progress

Beyond the Leaderboard: The Real Value of Strava Data

Most people use Strava just to check KOM/QOM rankings or compare speeds. But Strava records a wealth of valuable training data that can become a powerful training tool if you know how to interpret it.

Interpreting Key Metrics

1. Relative Effort

A heart-rate-based training load metric.

2. Weighted Average Power

Also called Normalized Power (NP), it accounts for the impact of power fluctuations.

• Average Power vs. Weighted Average Power: If the difference is large, it means your riding pace is inconsistent
• Variability Index: NP / AP, the closer to 1.0, the more consistent
• Goal: For steady riding, VI should be between 1.0-1.05

3. Intensity Factor

IF = NP / FTP

4. TSS (Training Stress Score)

Training stress score, combining time and intensity.

• Daily TSS Reference:

  • Easy recovery ride: 30-50
  • General training: 50-100
  • High-intensity day: 100-200
  • Race day: 200-400

• Weekly TSS Reference:

  • Amateur rider: 300-500
  • Serious training: 500-800
  • Semi-professional: 800-1200

Segment Analysis

How to Use Segments

1. Track progress: Compare performances on the same segment across different dates
2. Analyze pacing: See which sections you lose the most speed
3. Compare heart rate: Check whether heart rate drops at the same speed (an indicator of fitness improvement)

Notes

• Don’t obsess over KOM rankings
• Wind and traffic can significantly affect segment times
• Compare against yourself, not others

Long-Term Trend Analysis

Fitness & Freshness (Premium Feature)

• Fitness: Accumulation of long-term training load
• Fatigue: Short-term training load
• Form: Fitness - Fatigue
• Before a race, Form should be positive (indicating adequate rest)

Metrics to Track Yourself

Record the following data monthly:

1. Total riding distance
2. Total elevation gain
3. Average NP per ride
4. Best time on a fixed segment
5. FTP test results
