Garmin Frisbee Analysis

Analyze Garmin health and performance data specifically for Ultimate Frisbee players. Generate interactive HTML dashboards for post-game review, tournament fatigue tracking, training load optimization, and season-long trend comparison.

Two Installation Paths

  1. Clawdbot Skill (this guide) — Use with Clawdbot for natural language queries and proactive monitoring
  2. MCP Server (see MCP setup guide) — Use with Claude Desktop as an MCP server

Setup (first time only)

1. Install Dependencies

pip3 install -r requirements.txt

Pinned versions are in requirements.txt: - garminconnect>=0.2.19 — Garmin Connect API client - fitparse>=3.2.0 — FIT file parsing for activity data - gpxpy>=1.3.5 — GPX file parsing

2. Configure Credentials

Why email + password? Garmin does not expose a public OAuth API. The garminconnect library authenticates via Garmin's SSO, the same flow as the Garmin Connect mobile app. The password is used once during login and is never written to disk or logged. The resulting session token is then stored locally at ~/.clawdbot/garmin/ (permissions 700); all subsequent API requests use that token, not the password.

Set GARMIN_EMAIL and GARMIN_PASSWORD in your shell profile (~/.zshrc or ~/.bashrc):

export GARMIN_EMAIL="[email protected]"
export GARMIN_PASSWORD="your-password"

3. Authenticate

python3 scripts/garmin_auth.py login
python3 scripts/garmin_auth.py status   # verify

Frisbee Scripts

Post-Game / Post-Training Analysis

Analyze a single activity in depth: sprints, speed, heart rate zones.

# Most recent activity
python3 scripts/frisbee_activity.py --latest

# Specific date
python3 scripts/frisbee_activity.py --date 2026-03-08

# Specific activity ID
python3 scripts/frisbee_activity.py --activity-id 12345678

# Save to file
python3 scripts/frisbee_activity.py --latest --output ~/Desktop/game.html

Dashboard includes: - Summary cards: duration, distance, sprint count, top speed, sprint fatigue index, high-intensity distance - Speed timeline with sprint highlight bands - Sprint peak speed trend (detects fatigue: are later sprints slower?) - Heart rate zone distribution (Zone 1–6)

Sprint detection: speed > 14.4 km/h sustained ≥ 2 seconds. Sprint Fatigue Index: last 3 sprint peaks ÷ first 3 sprint peaks. < 0.85 = significant fatigue.

Tournament Review Dashboard

Full overview of a multi-day tournament: fatigue curve, game intensity, heart rate recovery, overnight sleep/HRV.

python3 scripts/frisbee_tournament.py 
  --start 2026-03-08 
  --end 2026-03-10 
  --name "Spring Tournament 2026" 
  --output ~/Desktop/tournament.html

Dashboard includes: - Body Battery fatigue curve across tournament days (includes day-before baseline) - Per-game avg/max heart rate comparison - Heart Rate Recovery curves post-game (30 min window, all games overlaid) - Overnight sleep hours + HRV per tournament night - Activity table with all detected games

Comparison Analysis

Compare training sessions, games, or the full season.

# Training vs training (last 90 days)
python3 scripts/frisbee_compare.py --mode training --days 90

# Game vs game
python3 scripts/frisbee_compare.py --mode tournament --days 180

# Training intensity vs game intensity
python3 scripts/frisbee_compare.py --mode cross --days 60

# Full season overview
python3 scripts/frisbee_compare.py --mode season --days 180

# Save output
python3 scripts/frisbee_compare.py --mode season --days 180 --output ~/Desktop/season.html

Activity classification uses name keywords: - Game: game, match, tournament, vs, finals - Training: practice, training, train, drill, scrimmage

Dashboard includes: - Top speed trend over time (training vs game color-coded in cross mode) - Avg heart rate per activity (color by intensity) - Morning HRV on day of each activity - Volume trend: duration + distance over time - Full activity table

Answering Frisbee Questions

Player asks Script What to report
"How many sprints did I hit?" frisbee_activity.py --latest sprint_count, sprint fatigue index
"What was my top speed?" frisbee_activity.py --latest top_speed_kmh from summary
"Was I fatigued at the end?" frisbee_activity.py --latest sprint_fatigue_index < 0.85 = yes
"How long was my heart rate elevated?" frisbee_activity.py --latest Zone 4-6 time percentage
"Did I recover fast enough between points?" frisbee_tournament.py HRR curves, slope comparison
"Was I ready for the tournament?" frisbee_tournament.py Pre-game Body Battery values
"Is my training intense enough?" frisbee_compare.py --mode cross Avg HR: training vs game
"Am I improving this season?" frisbee_compare.py --mode season Top speed + HRV trends
"How did I sleep during the tournament?" frisbee_tournament.py Recovery nights chart

Key Frisbee Metrics Explained

Sprint Fatigue Index

Ratio of last 3 sprint peak speeds to first 3: ≥ 0.95 stable, 0.85–0.95 mild decline, < 0.85 significant fatigue. Use this to judge if you're losing speed output as the game progresses.

Heart Rate Recovery (HRR)

How fast your HR drops after game ends. Steeper curve = better cardiovascular fitness and recovery. Flatter curves in later games of a tournament = cumulative fatigue.

Body Battery (0–100)

Pre-game value is the key readiness indicator. ≥ 70 = ready to go, 50–69 = manageable, < 50 = compromised performance likely.

Heart Rate Zones

  • Zone 4 (70–80% max): Sustained hard effort — hallmark of well-executed frisbee
  • Zone 5–6 (80–100% max): Explosive sprints and close contests
  • High Zone 4–6 in training = adequate game-prep intensity

Troubleshooting

  • "FIT file download failed": Check activity ID; some activity types may not export FIT
  • No sprints detected: Activity may not include speed data, or you used a non-GPS mode
  • HRR chart empty: Intraday HR not available for that date; ensure "All-day HR monitoring" is on in Garmin settings
  • Activities not classified: Name your activities with keywords like "game vs X" or "practice" — see classification keywords above
  • Tokens expired: Re-run python3 scripts/garmin_auth.py login

Privacy & Security

Credentials - GARMIN_EMAIL and GARMIN_PASSWORD are read from environment variables at runtime only - The Garmin password is never written to disk or logged — used only during the authentication step, then discarded - No config file stores credentials

Session tokens - Stored in ~/.clawdbot/garmin/ with directory permissions 700 (owner read/write/execute only) - Managed by the garth library (part of garminconnect); format is an opaque token bundle, not plaintext password - To revoke: rm -rf ~/.clawdbot/garmin/ — next login will re-authenticate

Network - Credentials are used only to authenticate with Garmin Connect and are not transmitted to any third-party service - All API calls go to connect.garmin.com only - Generated HTML dashboards load Chart.js from cdn.jsdelivr.net (versions pinned: [email protected], [email protected]) — requires internet access when viewing dashboards
