Section 11 — Open Protocol for AI Endurance Coaching (ChatGPT, Claude, Grok, Mistral)

I’ve been working on a structured protocol that makes AI endurance coaching consistent, reliable, and moveable, that works with any AI/LLM and is free.

Sharing it here since it builds on ideas from this community.

Section 11 — a deterministic protocol that forces AI systems to fetch your Intervals.icu data, follow evidence-based frameworks, and give auditable recommendations.

What it does: * Auto-fetches your training data via JSON mirror (Also manual option) * Structured response format: session details → training load context → interpretation * Works across ChatGPT, Claude, Grok, Mistral (tested)

What’s included: * SECTION_11.md — The complete protocol (11 A/B/C) * DOSSIER_TEMPLATE.md — Your athlete profile template * sync.py — Script to sync Intervals.icu → GitHub JSON * Setup guides for auto-sync and manual export

Quick start: 1. Fork the repo 2. Add your Intervals.icu API key as GitHub secret 3. Enable the sync workflow 4. Copy instructions into ChatGPT/Claude Project 5. Ask “How was today’s workout?”

Full setup: GitHub - CrankAddict/section-11: Evidence-based AI endurance coaching protocol. Deterministic guidance for any LLM (ChatGPT, Claude, Gemini, Grok, Mistral, etc.) with Intervals.icu integration.
