About Watts Per Kilogram

Watts per kilogram (W/kg) is a key metric in cycling performance. It represents your power output relative to your body weight, making it useful for comparing cyclists of different sizes.

FTP (Functional Threshold Power) is the highest power you can maintain for approximately one hour. It's typically determined through a 20-minute time trial or similar test.

Percentile rankings are based on general cycling population data. Higher W/kg values indicate better power-to-weight ratios.
