What to write
A report with real detail is more useful than a one-line note. It does not need to be long, but it should give the facts: what you did, what changed, and how it felt.
Useful details
The best reports include both the actual work and how it felt, especially when workout data is incomplete or looks strange.
- what you actually did: for example, 6 × 800 m, 2 minutes easy jog recovery, then 4 × 100 m strides;
- what differed from the plan: fewer reps, longer recovery, different pace, a pause, a stop, or shifting part of the session to another day;
- how hard it felt: easy, controlled, hard, or close to the limit;
- pain, tightness, unusual soreness, or discomfort;
- fatigue, stress, illness, heat, travel, or other outside factors;
- why pace, power, heart rate, or intervals looked different from expected;
- device issues: wrong sport type, missing intervals, missing metrics, or strange data.
