.FIT File Extension

A .FIT file is a Garmin Activity File, created by Garmin.

Open with Garmin Training Center (Discontinued). Available for Windows and Mac.

What is a .FIT file?

A .FIT file is a special type of file that is used by Garmin GPS devices, which are often used by people who enjoy outdoor sports like running or biking. These devices help track where you go, how fast you're moving, and how long you're active. The information from your activities, like your route, how long you were active, and other details, gets saved into a .FIT file.

Even though the Garmin Training Center program that used to open these files is no longer available, you can still use Garmin's online service, Garmin Connect, to open and view your .FIT files. Garmin Connect is a website where you can upload the .FIT files from your device. Once uploaded, you can see a map of where you've been, find out how far you went, how long it took, and even how many calories you might have burned during your activity. This is a great way for people to keep track of their fitness progress over time.

The .FIT file is quite similar to another file type called .TCX, but they are used in slightly different ways. Both are about recording and reviewing your physical activities, but they might store that information a bit differently.

In summary, if you have a Garmin GPS device and you like to keep track of your runs, bike rides, or other activities, the .FIT file is how your device saves your activity data. You can then upload these files to Garmin Connect on the web to see detailed information about your activities and track your fitness progress over time.
