What is a .pwx file?
File extension details and usage information
The PWX file format is a specialized XML-based data format developed by TrainingPeaks for the exchange of athletic performance data. It is primarily used by endurance athletes, coaches, and fitness enthusiasts to record and analyze workout metrics such as heart rate, power output, cadence, speed, distance, and GPS coordinates. Unlike simpler formats, PWX is designed to handle high-resolution data streams from various sensors simultaneously. It serves as a bridge between fitness hardware, such as Garmin or Suunto devices, and training analysis software. The format allows for detailed post-workout analysis, enabling users to track their progress over time, calculate training stress scores, and plan future sessions. Because it is based on XML, it is structured and can be parsed by various third-party applications, though it has largely been superseded in some contexts by the FIT format. It remains a standard for users of the TrainingPeaks ecosystem and compatible platforms for importing historical workout data.
