How an LLM can improve your run coaching loop

Where LLMs help most

• Spot patterns in your recent blocks (missed long runs, intensity spikes, taper timing).
• Turn metric changes into plain-English guidance you can execute tomorrow.
• Generate alternatives when life constraints change your plan mid-week.

Guardrails that matter

• Use your own training history and race context as the primary signal.
• Prefer conservative progression over aggressive jumps in volume or intensity.
• Treat LLM output as a recommendation layer, not medical advice.

A practical workflow

1. Sync recent runs and inspect PB progression + readiness + block comparison.
2. Ask the LLM for 2-3 plan options with pros/cons based on your target race.
3. Choose one option, then review outcomes weekly against the same charts.
