What an adaptive training plan changes
An adaptive plan revises upcoming work using completed training, recovery and current availability. It should explain which session changes and why. The goal and phase provide context, but neither a long run nor a race date must be preserved at the expense of health or recovery.
Worked schedule example
Suppose a runner normally has an easy Monday run, Tuesday intervals, an easy Thursday run and a Sunday long run. Work travel removes Tuesday and Thursday. One reasonable option is to omit the intervals and retain an appropriate easy run and a bounded Sunday session if recovery is normal. Another is to shorten Sunday when travel has also reduced sleep. The correct choice depends on current evidence; there is no requirement to squeeze four sessions into two days.
Check the adaptation
Compare the revised week with recent completed work. Confirm there is space around demanding sessions, the long run remains proportionate and the changes are understandable. Review how ordinary movement, effort and recovery respond before progressing.
A wearable can contribute information, but one score cannot decide whether illness, pain or fatigue is medically significant. General training rules cannot provide diagnosis or clearance. Use the training log to record the decision and the comeback planner after a longer interruption.
