## What it does

The plugin bundles four skills: plan generation (`training-plan`), data sync (`strava-sync`), weekly analysis (`running-coach`), and progress dashboard (`training-dashboard`). Plans factor in race distance, goal time, current weekly mileage, and race date; `calculate_paces.py` computes training zones, `interval_calculator.py` calculates interval distances. Weekly analysis compares planned versus actual paces, heart rate zones, and volume, then provides specific recommendations.

\`strava-sync` pulls activities via the Strava MCP server—pace, heart rate, power, cadence, elevation gain, lap data—and saves them to `training-log/week-n.md`. You can also create manual markdown entries or describe workouts conversationally. Python 3.8+ is required for pace scripts; Strava integration needs Node.js 18+ and MCP server configuration in `~/.claude/config.json`.

Periodization principles and workout guidelines live in `references/coaches-guide.md`; coaching session notes go into `coaching-log/`.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install running-race-coach@claude-community
```

## When to use it
- generate a 10-week half marathon plan with a goal time
- sync recent runs from Strava and structure them by week
- compare planned versus actual workouts and get pace and heart rate feedback
- calculate pace zones for intervals and threshold runs
- track training progress toward race day

## Example prompts
- Create a 10-week 10K training plan for a 45:00 goal, current mileage 30K per week
- Sync my last 7 days of training from Strava
- Analyze my week: compare plan versus actual and give recommendations

# Claude Running Race Coach

An AI-powered running coach built for [Claude Code](https://code.claude.com/) and [Claude Desktop](https://claude.ai/download) using the [Skills framework](https://code.claude.com/docs/skills). This project demonstrates how to combine Claude's capabilities with specialized training knowledge and training data to provide personalized running coaching assistance. Distributed as a plugin for easy installation.

**For usage instructions, see [running-race-coach/README.md](running-race-coach/README.md).**

## Overview

Claude Running Race Coach uses Claude Code's Skills framework to provide intelligent running coaching that includes:
- Evidence-based training plan generation
- Multi-platform training data integration (Strava, Garmin, manual entry, conversational)
- Weekly training analysis and coaching feedback
- Scientific pace calculation and workout planning

## Skills Architecture

This project leverages Claude Code's [Skills framework](https://code.claude.com/docs/skills), which allows Claude to follow structured workflows for specific domains. Each skill is a combination of:

### 1. Skill Definition (`SKILL.md`)

Each `SKILL.md` file defines:
- **Invocation patterns**: Keywords and phrases that trigger the skill
- **Workflow steps**: Structured process Claude follows
- **Best practices**: Domain-specific knowledge and principles
- **Tool usage**: When to use Python scripts or MCP servers
- **Output format**: How to structure the results

### 2. Reference Documentation

The `references/` directory contains in-depth knowledge that Claude loads into context when needed. For example:
- **coaches-guide.md**: Comprehensive training principles, periodization strategies, and workout guidelines

### 3. Executable Tools

Python scripts in the `scripts/` directories provide:
- **calculate_paces.py**: Calculates training pace zones from race goal times
- **interval_calculator.py**: Computes total distances for interval workouts

These are executed via Claude Code's terminal integration.

### 4. Integration with MCP Servers

Skills can leverage Model Context Protocol (MCP) servers for external data:
- **Strava MCP server**: Fetches activity data, athlete info, and statistics
- Extensible to other platforms (Garmin, Apple Health, etc.)

## How It Works

### Training Plan Generation

When a user requests a training plan:
1. **training-plan** skill is invoked
2. Claude gathers requirements (race distance, goal time, current mileage, race date)
3. Executes `calculate_paces.py` to determine training zones
4. Applies periodization principles from `coaches-guide.md`
5. Generates structured markdown training plan
