Free Triathlon Training Log Template

Track every swim, bike, and run session. Monitor your recovery, adjust your training, and build confidence week after week.

Why Keep a Training Log?

A training log is the simplest tool that separates athletes who improve from those who stagnate. Writing down your sessions forces you to reflect on what works, what doesn't, and what to change.

  • Track your volume and intensity across all three disciplines
  • Spot patterns between training load, fatigue, and performance
  • Stay motivated by seeing your consistency and progress over time
  • Catch early signs of overtraining before they become injuries
  • Connect your nutrition and sleep quality to how you perform

What Should You Track?

A good triathlon training log captures three layers of data: what you did, how your body responded, and how your week went overall.

Session Data

Discipline, duration, distance, intensity zone (Z1–Z5), RPE (1–10), whether it was a key workout, and quick notes on how it felt.

Body Signals

Resting heart rate, sleep quality (1–5), energy level (1–5), body weight, and any soreness or fatigue indicators.

Weekly Review

Total hours per sport, planned vs. actual volume, motivation level, what went well, and what to improve next week.

What's Inside the Template?

One A4 page per week with everything you need: daily session tracking, weekly volume summary, body metrics, and reflection notes. Print it, pin it, fill it in.

Frequently Asked Questions

Should I use a paper log or a digital app?

Both work. Paper is better for reflection — the act of writing slows you down and forces you to think. Digital is better for analysis and long-term tracking. Many athletes use both: a paper log for daily reflection and a watch/app for the raw data.

How often should I fill in my training log?

Ideally, fill in each session immediately after training while the details are fresh. Do the weekly review every Sunday evening — it takes 5 minutes and sets you up for the next week.

What is RPE and why should I track it?

RPE stands for Rate of Perceived Exertion, a 1–10 scale of how hard a session felt. It captures what heart rate and pace can't: stress, fatigue, motivation, and conditions. Tracking RPE alongside zones reveals when your body is ready to push and when it needs rest.
