This data set contains logged training sessions of a hobby athlete. Each session is logged at a resolution of one second, containing
- Time
- Heart Rate (bpm)
- Speed (km/h)
- Pace (min/km)
- Cadence (steps/minute)
- Altitude (m)
- Distance (m)
The device used to log the runs (the discontinued Polar M400 running watch) also creates columns for additional metrics that it doesn't log. These are left blank in the files. The data is provided as gzipped CSV files. Note that no data cleaning was attempted. This means that the data contains outliers and measurement errors. Below you see a sample plot representing the altitude profile of 20 kilometers run, including a number of apparent measurement errors.
The data set contains sessions of various distances ranging from a few kilometers to 20+ kilometers.
