fit is a Go package that implements decoding and encoding of the Flexible and Interoperable Data Transfer (FIT) Protocol. Fit is a "compact binary format designed for storing and sharing data from sport, fitness and health devices". Fit files are created by newer GPS enabled Garmin sport watches and cycling computers, such as the Forerunner/Edge/Fenix series.
