Building a Running Training Log: How Effective Record-Keeping Promotes Long-Term Progress

Introduction

Almost without exception, elite runners keep a training log. Japanese marathon legend Naoko Takahashi and British long-distance star Paula Radcliffe have both emphasized the importance of a training log in interviews. However, among Taiwanese runners, the proportion who systematically record their training remains low. Many rely only on their watch’s automatic records, overlooking the subjective information that is equally important beyond the numbers.

A good training log is a mirror, allowing you to see your past, present, and future training patterns. This article provides a practical log framework suitable for Taiwanese runners.

What Should You Record in a Log?

Mandatory Items (Complete within 5 minutes after each training session)

Optional Items (Compile once a week)

• Morning Resting Heart Rate: Measured before getting up; a higher reading (+5 bpm or more) indicates fatigue accumulation
• Body Weight: Long-term trends matter more than daily fluctuations
• Sleep Hours and Quality (self-rated 1–5)
• Muscle Soreness Locations: Record on a body chart to track any tendency toward chronic pain
• Weather Conditions: Temperature, humidity, wind speed—important background information for explaining abnormal heart rate

Race Records (Complete after each race)

• Pre-race condition (sleep, diet, nervousness level)
• Split pace records (every 5 km)
• Fueling strategy execution
• Post-race physical response (sore areas, recovery speed)
• Three reflections: what went well, what went poorly, what to improve next time

Choosing a Logging Tool

Digital Tool Comparison

Recommended Approach: A Dual-Track System

• Automatic Data Layer: Garmin Connect / Strava records all objective numbers
• Subjective Reflection Layer: Google Sheets or paper records feelings, notes, and weekly reviews

The two layers complement each other: objective data explains “what happened,” while subjective records explain “why it happened that way.”

How to Discover Patterns in Your Log?

Monthly Review (Last day of each month, 15 minutes)

Answer the following questions:

1. Did this month’s mileage reach at least 80% of the plan? If not, what was the main obstacle?
2. What is the trend in resting heart rate? An upward trend indicates overtraining or illness
3. Is there any recurring sore spot? Early detection, early treatment
4. What was the most satisfying training session this month? Analyze the reasons and try to replicate the conditions
5. What was the worst training session this month? Identify the triggers and avoid them next month

Annual Review (Every December or after the season ends)

• Plot a line chart of weekly mileage across the year to identify training peaks and valleys
• Tally the number of injury days and injury locations
• Compare target results with actual results
• Evaluate the execution rate of the training plan

Common Pitfalls in Logging

• Over-logging becomes a burden: Setting up too many fields at the start leads to giving up after a few weeks. It is recommended to start with just three basic fields: “date, distance, RPE”
• Only recording good workouts: Bad workouts are equally worth recording—perhaps even more so
• Lacking subjective descriptions: A purely numerical log cannot reveal the story behind the numbers; a few sentences of notes often explain abnormal data
• Never reviewing: Recording without ever looking back is the same as not recording at all

Practical Advice

• Make logging a fixed post-training ritual, as indispensable as cooling down after a workout
• Use the 10-minute rule: if you think you have no time to log, just record the three most important fields
• Once a month, read a log entry from 3 months ago—you will be surprised at how many details you have forgotten and how much you have improved
• Increase logging frequency during race preparation, especially in the final 4 weeks before the race; daily condition records are crucial then

Conclusion

A training log is a record of the long-term conversation between you and your body. It will not make you run faster—but it will help you train smarter. When you look back a few months from now, you will thank yourself for spending 5 minutes logging today.
