+## Garmin Run Data – ETL Pipeline Update
+
+This ETL pipeline processes `Garmin_run_data.csv` and includes:
+
+### Data cleaning:
+- Removes duplicate rows
+- Standardizes column names (lowercase, underscores)
+- Converts timestamps to datetime
+- Fills missing numeric values with column means
+- Removes outliers in `heart_rate` (keeps values between 30–220 bpm)
+- Converts distance from meters to kilometers
+- Converts speed from m/s to km/h
+
+### Data aggregation:
+- Groups data by year and week
+- Calculates total runs, total distance (km), average speed (km/h), and average pace (min/km) per week
+
+### Outputs:
+- `cleaned_garmin_run_data.csv` → cleaned dataset
