FIT test files

This is a corpus of Flexible and Interoperable Data Transfer (FIT) Protocol files to support interoperability testing of .FIT file decoding, parsing, analysing, and visualization.

FIT files are a data file format used by - among others - COROS, Garmin, Suunto, Zwift, and Wahoo for sharing health, fitness, and sport data.

AllFitMessageTypes.fit is a synthetic test vector that contains at least one example of each FIT message supported by the Garmin - FIT C# SDK.
