Convert TCX to FIT

Understanding TCX and FIT file formats

The TCX (Training Center XML) is a file format developed by Garmin, a leading company in GPS technology. It is primarily used for fitness tracking, storing data such as heart rate, speed, distance, and location. The TCX format is based on XML, making it easy to read and write by both humans and machines.

On the other hand, the FIT (Flexible and Interoperable Data Transfer) format is also a product of Garmin. It is a more compact binary format designed for storing physiological and geographical data. It is more efficient and flexible than TCX, making it the preferred choice for many fitness devices and applications.

Converting a TCX file to FIT format can be useful when you want to use your data with devices or applications that only support the FIT format. There are several tools available for this conversion, but one of the most reliable and easy to use is GPSBabel.
