A FIT file (Flexible and Interoperable Data Transfer) is a compact binary file format created by Garmin to store fitness, workout, and GPS tracking data. It holds metrics like heart rate, route coordinates, cadence, power, and timestamps generated by sports watches and cycling computers and it is used natively by brands like Garmin and Wahoo to log training sessions.
Here a little WIP, as usual driven by @tonfilm ai skills, it reads a .fit files and extrapolates its data, then plots it in a simple graphic interface.
