+# Strava Master & Weekly Summary Dataset
+
+Personal Strava export processed on **2025-05-04**  
+Provides per-activity master table and weekly aggregations with intensity metrics.

+## Files
+
+| File | Rows | Description |
+|------|------|-------------|

+
+## Column definitions (master)
+
+| Column | `dtype` | Description |
+|--------|---------|-------------|
+| `activity_id` | `int64` | Unique Strava activity ID |
+| `name` | `string` | Activity title on Strava |
+| `sport` | `category` | Sport type (Run / Ride / Swim / Walk / … ) |
+| `date` | `datetime64[ns]` | Local start time |
+| `distance_km` | `float32` | Distance (metres → **km**) |
+| `elapsed_hr` | `float32` | Elapsed time (sec → **h**; incl. stops) |
+| `moving_hr` | `float32` | Moving time (sec → **h**) |
+| `elevation_gain_m` | `float32` | Positive elevation gain (m) |
+| `elevation_loss_m` | `float32` | Negative elevation (descent, m) |
+| `average_speed_kph` | `float32` | Moving speed (km h-¹) |
+| `max_speed_kph` | `float32` | Max speed (km h-¹) |
+| `average_hr` | `float32` | Avg heart-rate (bpm); *NaN* if no sensor |
+| `max_hr` | `int16` | Max heart-rate (bpm) |
+| `average_cadence` | `float32` | Avg cadence (rpm); bike-runs mixed |
+| `max_cadence` | `int16` | Max cadence (rpm) |
+| `intensity_level` | `float32` | Avg HR ÷ **LTHR (165 bpm)** → 0.50–1.10 |
+| `training_category` | `category` | HR zone label: `Z1-2`, `Z3`, `Z4`, `Z5`, `NoHR` |
+| `trimp` | `float32` | Banister TRIMP = `moving_hr × intensity_level × 50` |
+| `pace_min_per_km` | `float32` | Pace (min km-¹); *NaN* for non-run sports |
+| `commute` | `boolean` | Marked as commute on Strava |
+| `gear` | `string` | Bike / Shoes used (if set) |
+| `calories_kcal` | `float32` | Calories reported by Strava |
+| `weather` | `string` | Weather summary (if available) |
+| `temperature_c` | `float32` | Avg temperature (°C) |
+| `relative_effort` | `Int32` | Strava Relative Effort score |
+| `filename` | `string` | Original FIT/GPX filename (metadata only) |
+| `gpx_path` | `string | None` | Path to GPX in `routes/` (not included if `None`) |
+
+> **Note**  
+> * All numeric time/ distance columns are converted to SI units (hours & kilometres) for easy aggregation.  
+> * Empty sensor data (e.g. HR-less activities) are stored as **`NaN`** so they don’t skew means.  
+> * `training_category` bins: Z1-2 < 0.79, Z3 < 0.89, Z4 < 0.95, Z5 ≥ 0.95 of LTHR.  
+> * `gpx_path` points to a GeoJSON-converted route if the original GPX was processed; raw GPS files are **not** in the repo for privacy.

+
+## Processing pipeline
+
+1. **Header translation** : JP CSV → EN headers (custom script)  
+2. **Unit conversion** : distance m→km, time s→h  
+3. **Intensity & TRIMP** : LTHR = 165 bpm, zones Z1-2/3/4/5  
+4. **Weekly aggregation** via pandas `groupby`  
+
+Full code is available in `notebooks/` and `make_dataset.py` inside the GitHub repo.

+## Usage example
+
+```python
+from datasets import load_dataset
+ds = load_dataset("Benj-samurai/strava_dataset",
+                  data_files="strava_master_enhanced.parquet")
+df = ds["train"].to_pandas()
+print(df.head())
+```

+- **Raw FIT/GPX files are _not_ included.**
+- **No exact home coordinates**  
+  All activity start points are shifted by ≥ 200 m to obscure the true home location.
