Perform the following steps to end a ride:
- Wait until the virtual bike computer shows zero speed
- Open mod menu using F5 key
- Select option End and save current activity
You will see a summary of your activity and will be given the option to keep or discard the ride.
If you keep it, the ride will be saved to a FIT file in the user data directory located at My Documents\Rockstar Games\GTA V\Activities. Manually upload the FIT file to your favorite sport app.
Along with the FIT file you’ll find the screen shots taken during the ride, a map and a small elevation profile image.
