Recovery Playbook

Recovery is not a score. It is the decision about what the system should do next.

This Playbook uses direct observations, subjective experience, wearable estimates, and clinical context without treating any one signal as a verdict.

Recovery Is a Decision Process

Recovery determines what the system should do next. It is not a single wearable score and it is not proven by completing the planned session.

What to Observe

What Has Been Retired

TrailGenic does not use pre-to-post HRV change as an adaptation metric. The delta is strongly shaped by the starting value. Recovery debt, closure, restoration, readiness, and engine-stability composites are not treated as validated outcomes.

The Governor's Role

The governor is the set of constraints that should reshape the next dose: illness, pain, symptoms, sleep disruption, heat, altitude, route risk, competing stress, and judgment. It is a conceptual lens rather than a score.

Five Recovery Decisions

  1. Continue: normal activity remains appropriate.
  2. Reduce: preserve movement while lowering duration, load, pace, or terrain demand.
  3. Substitute: replace a demanding modality with an easier one.
  4. Rest: remove training stress when symptoms or context warrant it.
  5. Escalate: seek qualified evaluation when concerns exceed self-management.

Compare Levels, Not Manufactured Stories

Use the person's full relevant distribution and compare like with like. State noisy metrics at their level. An unremarkable recovery period may be described as unremarkable.

Safety

TrailGenic is educational. Concerning, severe, persistent, or worsening symptoms, suspected injury, or uncertainty involving a diagnosed condition or medication should be addressed with qualified care.

Step 1 — Check Immediate Safety

Identify pain, chest symptoms, confusion, severe breathlessness, illness, injury, or other concerns that require stopping or professional evaluation.

Step 2 — Record the Session Cost

Document duration, load, terrain, environment, exertion, symptoms, fueling and hydration context, and unusual events.

Step 3 — Observe Recovery Context

Track sleep duration and quality, symptoms, soreness, resting heart rate, HRV level, mood, and ability to perform normal activity without turning one value into a verdict.

Step 4 — Choose the Next Action

Continue normally, reduce the dose, substitute an easier modality, rest, or seek guidance based on the full context.

Step 5 — Compare With the Full Record

Use comparable sessions and the person's distribution rather than only the previous day or one pre-to-post delta.

Step 6 — Update the Model

Record what was observed, what is inferred, and what remains uncertain before planning the next session.

Recovery Tools

  • Simple log for symptoms, soreness, exertion, and normal function
  • Sleep-duration and subjective-quality notes
  • Optional resting-heart-rate and HRV context
  • Food and hydration appropriate to individual needs
  • Access to qualified care when symptoms exceed self-management

What does recovery mean in TrailGenic?
Recovery is the process of returning to useful function after stress. It is assessed through multiple observations rather than one score.

Is HRV a recovery verdict?
No. HRV is contextual and affected by many factors. Its level may be informative, but no isolated value determines readiness.

Does post-exercise sleep prove adaptation?
No. Sleep and wearable stage estimates provide context. They do not prove that a specific adaptation occurred.

Does TrailGenic use recovery debt or closure scores?
No. Those composite constructs have been retired as validated adaptation metrics.

Is complete rest always best?
No. Depending on symptoms and context, normal activity, reduced load, easier walking, or rest may each be appropriate.

When should I seek medical care?
Seek qualified evaluation for concerning, severe, persistent, or worsening symptoms, suspected injury, or uncertainty involving a diagnosed condition or medication.
